Enter the total number of particles and the molar mass of substance (g/mol) into the Mass From Particles Calculator. The calculator will evaluate and display the Mass.

## Mass From Particles Formula

The following formula is used to calculate the Mass From Particles.

Mp = P / 6.02214076e23 * mm

- Where Mp is the Mass From Particles (g)
- P is the total number of particles
- mm is the molar mass of substance (g/mol)

To calculate mass from the number of particles, divide the number of particles by Avogadro’s number, then multiply by the molar mass.

## How to Calculate Mass From Particles?

The following example problems outline how to calculate Mass From Particles.

Example Problem #1:

- First, determine the total number of particles.
- The total number of particles is given as: 15e24.

- Next, determine the molar mass of substance (g/mol).
- The molar mass of substance (g/mol) is provided as: 13.

- Finally, calculate the Mass From Particles using the equation above:

Mp = P / 6.02214076e23 * mm

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

Mp = 15e24 / 6.02214076e23 * 13 = 323.805 (g)

Example Problem #2:** **

For this problem, the variables needed are provided below:

total number of particles = 16e20

molar mass of substance (g/mol) = 40

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

Mp = P / 6.02214076e23 * mm** = ?**
