How many grams of solute are needed to make 250 mL of a 2.055 M NaCl solution?
30 grams
76.7 grams
300.081 grams
58.44 grams
Answer:
30grams
Explanation:
To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;
M = n÷ V
Where; M= Molarity or Molar concentration = 2.055M
n= number of moles= ?
V= Volume = 250mL
Volume in L is 250/1000 = 0.250L
n= M × V
n= 2.055 × 0.250
n= 0.51375moles
The mass is calculated using :
Mole (n) = mass (m) / molar mass (MM)
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mass = molar mass × mole
Mass = 58.5 × 0.51375
Mass = 30.0543
Therefore, the mass is 30grams

If you have a 20% sugar solution and a 45% sugar solution how does the 20%
solution compare to the 45% solution?
Answer:
It is 25% less
Explanation:
That is all i can say
A close comparison of the 20% solution to the 45% solution shows that the 20% solution is actually less than 50% of the 45% solution.
Arithmetically, you discover that the 20% solution is 25% or 0.25 (45% - 20%) less than the 45% solution.Comparatively, you can compute that the 20% solution actually represents 44.4% or 0.444 of the 45% solution (20% x 45%). The same result can be obtained by first dividing 20% by 45% and then multiplying the resulting dividend by 100.Thus, the result of the comparison shows that there is more sugar in the 45% solution than there is in the 20% sugar solution.

Water fleas (Cladocera) are small freshwater crustaceans. They are filter feeders can are about 3-5mm long. The outer carapace of a water flea is transparent so the internal organs can be observed. Caffeine raises the heart rate of humans. Hanna predicts caffeine will have the same effect on other organisms. She uses the water flea as her test subject in an experiment. Hanna introduces varying amounts of caffeine to water flea populations. Using a microscope, she measures the heart rate in beats per second of sample water fleas. She records the data in a table. As the concentration of caffeine increases, Hanna observes the water flea heart rate also increases. What is the hypothesis in Hanna’s experiment? A) Caffeine raises the heart rate of humans. B) Water fleas prefer caffeine over plain water. C) Caffeine increase the heart rate of the water flea. Eliminate D) The effects of caffeine are the same on all organisms.
Answer:
The Answer is C.
Explanation:
sorry i took awhile
The hypothesis is the part of the scientific method that is the supposition based on some observed data. In Hanna's experiment, "caffeine increase the heart rate of the water flea" is the hypothesis. Thus, option C is correct.
What is a hypothesis?The hypothesis has been defined as the conjecture that is proposed in a scientific method and is based on the speculations from the observed facts and information. It is proposed to perform the experiment and reach the conclusion of the reliability.
They are testable and are performed through the experimental design that includes the experimental and control group so that the collected evidence can be analyzed and proved to be true. In Hanna's experiment, the effect of caffeine on the heart rate of fleas is a hypothesis.
It is a hypothesis as it is based on the observed fact that caffeine increases the human heart rate. The caffeine acted as the independent variable and the heartbeat was the dependent variable that showed that water fleas have increased heartbeat if given caffeine.
Therefore, option C. caffeine increases heartbeat is the hypothesis.

Describe one reason why the solvent property of water is so important for living organisms (nature).
Answer:
Water is known as a universal solvent as it allows for lots of salts and gases to dissolve in it. Water is found between living tissues. This helps for vitamins, minerals and gases to dissolve in the cell. Because of this, the cell lives as it gets glucose and oxygen needed for respiration(to produce energy) .
Also water helps in transport of substances around the body.
The solvent property of water is very important for living organism due to its high dissolving power.
The solvent property of water is very important for living organisms because water dissolve large number of solutes in it and helps in the transportation from one place to another. Water is a polar substance which dissolves polar solutes in itself.
Water dissolve nutrients in itself and transport to the regions where it needed the most so we can say that the solvent property of water helps in the transportation of nutrients and other substance in the body of organisms.

Which cell type undergoes terminal differentiation?
A-epithelial cells
B-stem cells
C-heart cells
D-hair cells
Stem cells are the cell type that undergoes terminal differentiation.
STEM CELLS:
Stem cells are cells in animals that are capable of differentiating into any cell type. Differentiation of a cell implies that the cell becomes more specific in its function. Stem cells undergo mitotic division to produce one daughter cell that is a stem cell and another daughter cell that has differentiated. Stem cells undergo terminal differentiation into specific cell types such as epithelial cells, muscle cells, heart cells, hair cells, blood cells etc. Therefore, stem cells are the cell type that undergoes terminal differentiation.Learn more at: https://brainly.com/question/11161299?referrer=searchResults

Why don't we have a genome sequenced from Homo erectus?
(a) There isn't enough research funding to pay for it.
(b) DNA degrades over time and the fossils are too old.
(c) H. erectus DNA is too similar to ours to prevent contamination.
(d) No H. erectus fossils have been found in Germany, which is where the lab is located.
(e) None of the above; we do have a sequenced genome of H. erectus.
Answer: Homo erectus DNA is too similar to ours to prevent contamination.
Explanation:
Homo erectus fossils are known as the oldest form of early humans that had human like body structure with shorter arms and elongated legs and shorter arms. These features gave them the ability to walk and also run long distances.
The reason that we do not have a genome sequenced from Homo erectus is that their DNA is too similar to ours to prevent contamination. There are enough fund which could have been used to carry out the research but their similarities to human beings has been the source of concern.
Read the following claim. Life on Earth could not exist without decomposers. What evidence from the article supports this claim? Explain why the evidence supports this claim.
Answer:
Explanation:
It's hard to distinguish facts/ evidence from the article with only the statement ' Life on earth could not exist without decomposers', but taking that into consideration, it's best if you breakdown the information so you properly understand what it means.
Life on earth - refers to evolution of life on earth such as single celled organisms, eukaryotes, prokaryotes, bacteria and so on
could not exist - refers to the inability of it being there, it's presence is basically there/ not there
decomposers - is an organism that breaks down organic materials from dead organisms to obtain energy such as fungi, bacteria, worms and so forth.
You basically need to relate all the information you find in the 'article' to the statement they have made and which i have broken down for you above.

Help me plz !!!! A cat that weighs 55 N sits on the top of a cat tree. It is 2 m above a 110 N
dog. How does the mass of the animals relate to the force of gravity on
them?
O A. The mass of the 55 N cat is greater than the mass of the 110 N
dog.
B. The 55 N cat has less mass than the 110 N dog.
C. The 55 N cat has the same mass as the 110 N dog when it is in
the cat tree.
O D. The mass of the 55 N cat will be the same as the mass of the 110
N dog after it jumps to the ground.
Answer:
B. The 55 N cat has less mass than the 110 N dog.
Explanation:
Weight of an object refers to the product of its mass and the force of gravity. However, the greater that mass of an object, the greater the weight of that object.
In this case, the cat's weight is 55N while the dog's weight is 110N. This means that the dog has a greater mass than the cat or alternatively put, the 55 N cat has less mass than the 110 N dog.
Note that: if the gravitational effect is removed, the cat will contain lesser mass.
