Detailed Solution

The relationship between a chemical's mass and density is as follows.

$d = \frac{m}{V}$

Here d = density of a chemical
m = mass of a chemical
V = Volume of a chemical
- There is a relationship between mass and molecular weight of a chemical and it is as follows.
Mass of a chemical (m) = (n) (molecular weight)
Here m = mass of a chemical
n = number of moles of a chemical
MW = Molecular weight of a chemical

The molecular weight and density are related as:

$d = \frac{m}{V} d = \frac{n \times M W}{V}$

Where n is the number of moles of the substance and MM is the molecular weight.

We can calculate a chemical's density by multiplying and dividing its molecular weight by its number of moles and its volume, respectively.

Hence, option C is correct.
