Molar Volume Calculator
Top
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.

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

  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



    Answer  :  

    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.



    Answer  :  

    The molar volume of ice (solid water) is 353.83 m3/mol.
