Enter the molar mass and molar volume into the calculator to determine the density of a substance. The calculator provides the density in grams per liter (g/L).

G/Mol to Density Formula

The following formula is used to calculate the density from the molar mass and molar volume.

D = \frac{M}{V_m}

Variables:

  • D is the density (g/L)
  • M is the molar mass (g/mol)
  • V_m is the molar volume (L/mol)

To calculate the density, divide the molar mass (M) by the molar volume (V_m).

What is Density?

Density is a measure of mass per unit volume. It is an important property of a substance and can be used to identify materials, determine their stability and reactivity, and design processes for their use. In chemistry, density is often used in conjunction with molar mass and molar volume to describe the concentration of a substance in a given volume.

How to Calculate Density from G/Mol?

The following steps outline how to calculate the density from the molar mass and molar volume.


  1. First, determine the molar mass (M) in grams per mole (g/mol).
  2. Next, determine the molar volume (V_m) in liters per mole (L/mol).
  3. Use the formula from above: D = M / V_m.
  4. Finally, calculate the density (D) in grams per liter (g/L).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
