Question

relation between molarity and density
​

Answer 1

Molarity and density are different ways of expressing essentially the same thing. Whereas density is the mass of a solid, liquid or gas divided by its volume, molarity is the number of moles of solute per liter of solution. It makes some calculations easier, however, if all quantities are in units of density.

Answer 2

Explanation:

Whereas density is the mass of a solid, liquid or gas divided by its volume, molarity is the number of moles of solute per liter of solution. A mole of a compound is the atomic masses of its component atoms in grams, and a liter is a measure of volume, so molarity is also a measure of density.
