The molar volume of an element is the volume occupied by 1 mole (6 $\times$ 1023 atoms) of the element. It is very dependent on atomic radius and structure. Molar volume is inversely related to density.

The idea of molar volume of a gas is also used to find out the molar mass of a volatile liquid, because a volatile liquid may be made into a gas easily.
Molar Volume Calculator calculates the volume occupied by one mole of a substance at a given temperature and pressure.

## Steps for Molar volume calculator

Step 1 :

Read the problem carefully and list the values given.

Step 2 :

Apply the formula and substitute the values to get the molar volume value.

Molar Volume(Vm) = $\frac{Atomic\ Weight \times Molar\ Mass}{Density(\rho)}$

## Problems on Molar volume calculator

1. ### NaClO3 when heated decomposes to NaCl and O2, what volume of O2 at STP results from the decomposition of 42.6 grams NaClO3?

Step 1 :

Atomic weight = 96

Molar mass = 42.6 = 0.0426kg/mol

Density = 213 = 0.213kg/m3

Step 2 :

Substitute the values in the given formula.

Molar volume = $\frac{96 \times 0.0426}{0.213}$

Molar volume = 19.2

The molar volume of O2 is 19.2 m3/mol.

2. ### Calculate the molar volume of ice (solid water) whose density is 0.9167g/cm3 and atomic weight is 18.02g and molecular mass is given by 18g.

Step 1 :

Density = 0.9167 = 0.0009167 kg/m3

Atomic weight = 18.02

Molecular mass = 18 = 0.018 kg/mol

Step 2 :

Substitute the values in the given formula.

Molar volume = $\frac{18.02 \times 0.018}{0.0009167}$

Molar volume = 353.83 m3/mol.
