Enter the molar mass (g/mol) and the density (g/L) into the Chemistry Volume Calculator. The calculator will evaluate and display the Chemistry Volume. This calculator can also determine the molar mass or density if given the other variables.

Chemistry Volume Formula

The following formula is used to calculate the Chemistry Volume. 

Vchem = MM / D
  • Where Vchem is the Chemistry Volume (L)
  • MM is the molar mass (g/mol) 
  • D is the density (g/L) 

To calculate chemistry volume, divide the molar mass in grams per mole, by the density in grams per liter.

How to Calculate Chemistry Volume?

The following example problems outline how to calculate Chemistry Volume.

Example Problem #1:

  1. First, determine the molar mass (g/mol). The molar mass (g/mol) is given as 25.00.
  2. Next, determine the density (g/L). The density (g/L) is provided as 4.
  3. Finally, calculate the Chemistry Volume using the equation above: 

Vchem = MM / D

The values given above are inserted into the equation below:

Vchem = 25 / 4 = 6.25 (L)


Example Problem #2: 

The variables needed for this problem are provided below:

molar mass (g/mol) = 60

density (g/L) = 3

Entering these values and solving gives:

Vchem = 60 / 3 = 20 (L)
