Chemistry (Molar) Volume Formula
The following formula is used to calculate the Chemistry Volume (molar volume).
Vchem = MM / D
- Where Vchem is the molar volume (L/mol)
- MM is the molar mass (g/mol)
- D is the density (g/L)
To calculate chemistry volume (molar 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 (molar volume).
Example Problem #1:
- First, determine the molar mass (g/mol). The molar mass (g/mol) is given as 25.00.
- Next, determine the density (g/L). The density (g/L) is provided as 4.
- 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/mol)
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/mol)
