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:

  1. First, determine the total number of particles.
    • The total number of particles is given as: 15e24.
  2. Next, determine the molar mass of substance (g/mol).
    • The molar mass of substance (g/mol) is provided as: 13.
  3. 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.
