To find the mass you have to multiply the density and volume together
If you already have the mass you divide the mass by either the density or volume
What form do ionic compounds take when solid?
Answer:
lattices
Explanation:
Ionic compounds are crystalline solids under normal conditions, have high melting points, and form lattices at the macroscopic level. Almost all of these solids dissolve in water and conduct electricity when dissolved. These substances are known as electrolytes because they can conduct electricity when in solution.
hope this helps
the melting point of a substance is also the same as the:
Answer:
The melting point of a solid is the same as the freezing point of the liquid. At that temperature, the solid and liquid states of the substance are in equilibrium.
Pure gold: 1063
Pure silver: 961
Do gasses have a fixed volume
Answer:
No
Explanation: Gases have no fixed volume and no fixed shape. Gases expand to fill the space available. They can also be compressed into a very small space.

4. Evaluate: Look at the results of your experiment. What was the relationship between crumple zone rigidity, crumple zone deformation, and maximum force on the dummy?
Answer:
Explanation:
Start by restating the question.
So how is the crumple zone rigidity, crumple zone deformation , and the maximum force of the dummy similar, and how are they different?
The crumple zone increases, the crumple zone deformation increases then decreases then repeated in increasing and decreasing , and the maximum force decreases. Hope that helps!

Answer:
cellular respiration
Explanation:
An unknown material has a mass of 4.5 g and a volume of
6.75 cm3. What is the density
Answer:
0.67 cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 4.5 g
volume = 6.75 cm³
We have
[tex]density = \frac{4.5}{6.75} \\ = 0.6666666...[/tex]
We have the final answer as
0.67 cm³Hope this helps you

What is the molarity of 930 mL of LiCl solution that contains 139.9 g of LiCl?
O A. 3.5 mol/L
O B. 150 mol/L
hipotle and like
O C. 3.3 mol/L
O D. 3.5 x 10-3 mol/L
Answer:
3.5 mol/L
Explanation:
First convert the 139.9g of LiCl into moles of LiCl. Don't do the sig fig rule until the very end.
Second, take 930mL of LiCl and divide it by 1000 to convert it to liters.
Third use the molarity formula which is M=mol/L and divide 0.930L by 3.300773877mol and you will get 3.549219223. This is where the sig fig rule will come into play. 3.5mol/L is a reasonable answer for this problem.
Is density a characteristic property of water?
"Density is a characteristic property of water because the density of any sample of water (at the same temperature) is always the same. The density is 1 g/cm3." - Mazza

what if water didnt have a negative charge?
Explanation:
The water molecule has a tiny negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms due to the unequal sharing of electrons.
list 5 chemical properties of water??
Answer:
In the presence of a strong electron donor (strong reducing agent), water serves as an oxidizing agent. In the presence of a strong electron acceptor (strong oxidizing agent), water serves as a reducing agent. On-water reactions are a group of organic reactions that take place as an emulsion in water and have an unusual reaction rate acceleration compared with (i) the same reaction in an organic solvent, or (ii) the corresponding dry media reaction.Amphoteric nature : Water can act as both acid and base, which means that it is amphoteric in nature.Hydrolysis reaction : Water has a very strong hydrating tendency due to its dielectric constant. It dissolves many ionic compounds. Some covalent and ionic compounds can be hydrolyzed in water.Redox reactions : Electropositive elements reduce water to hydrogen molecule. Thus, water is a great source of hydrogen.List a few properties that elements in Group 1 have in common.
