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) 

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. 

Mp = P / 6.02214076e23 * mm = ?
