## Molar Mass From Density Formula

The following formula is used to calculate the Molar Mass From Density.

MM = (D*V * 1000) / n

- Where MM is the Molar Mass From Density (g/mole)
- n is the number of moles
- D is the density (kg/m^3)
- V is the volume (m^3)

To calculate the molar mass from density, multiply the density by the volume, then multiply by 1000 and divide by the number of moles.

## How to Calculate Molar Mass From Density?

The following example problems outline how to calculate Molar Mass From Density.

**Example Problem #1**

- First, determine the number of moles.
- The number of moles is calculated to be : 4.5.

- Next, determine the density (kg/m^3).
- The density (kg/m^3) is measured to be: 30.

- Next, determine the volume (m^3).
- The volume (m^3) is found to be: 300.

- Finally, calculate the Molar Mass From Density using the formula above:

MM = (D*V * 1000) / n

The values given above are inserted into the equation below and the solution is calculated:

MM = (4.5*30 * 1000) / 300 = 450 (g/mole)

**Example Problem #2**

The variables needed for this problem are provided below:

number of moles = 6

density (kg/m^3) = 7

volume (m^3) = 4

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

MM = (D*V / 1000) / n =** **(g/mole)
