The density of a liquid is 6.0g/cm3 , when it fills a container of volume 300cubic centimeters . What is the mass of the liquid in the container?
Answer:
1800g
Explanation:
b/c d=m/v
m=dv
m=300×6=1800g
The mass of the liquid in the container is equal to 1800 g.
What is the density?The density of an object can be described as the mass per unit volume of the object. The average density of any substance equals the total mass of the substance divided by its total volume.
The mathematical formula of the density can be expressed as follows:
The density of material = Mass/Volume
Mass = density × Volume
The S.I. unit of the density of any substance is Kg/m³ and it is an intrinsic property. If the size of the substance increases, the mass increases as well but the density of the substance will stay constant.
Give, the density of the liquid, d = 6.0 g/cm³
The volume of the container, V = 300 cm³
The mass of the liquid = 6 ×300 = 1800 g
Therefore, the mass of the liquid is equal to 1800 g.

How many total atoms of oxygen are present in the molecules represented here?
Answer:
The answer is 36 atoms
Explanation: I took the test and i got 100%
There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".
We have the expression "6 C₆H₁₂O₆", which represents 6 molecules of C₆H₁₂O₆.
The subscripts are the atomicities of the element, that is, the number of atoms of each element in 1 molecule.
There are 6 atoms of oxygen per molecule of C₆H₁₂O₆. Considering that there are 6 molecules, the total number of atoms of oxygen are:
[tex]6 Molecules \times \frac{6\ O\ atoms}{1Molecule} = 36\ O\ atoms[/tex]
There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".

Answer:
ITS CALLED RASH
Explanation:
Compare the types of elements in covalent molecular compounds vs. ionic compounds. explain
Answer:
Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are (usually) formed when a metal reacts with a nonmetal (or a polyatomic ion). Covalent compounds are formed when two nonmetals react with each other.
Explanation:
Hope this helps.
the mass number for an atom is numerically equal to which quantity
Answer:
The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.
Explanation:
protons
The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.
3.7x10^45 molecules of hydrogen gas = how many grams of hydrogen gas
Since we weren't given the moles of hydrogen, we have to find it. However, we can do it all in one step if we set up the equation correctly.
Since Mass = moles × molar mass
& Moles = #molecules ÷ Avogadro's Number
∴ mass = (#molecules ÷ Avogadro's Number) × molar mass
= (3.7 × 10⁴⁵ mcules ÷ (6.022 × 10²³ mcules/mole)) × 1.008 g/mol)
= 6.19 × 10²¹ g

Which element in Fe(NO3) is a metal?
O
N
Fe
Answer:
Explanation:
Most periodic tables have a staircase thick line on their right side. This line separates the metals from the non metals.
O (oxygen) and N (nitrogen) are on the right side of the staircase.
Fe is on the left.
Those elements on the right side of the staircase are non metals.
Those elements on the left of the staircase are metals, so Fe is a metal.
