Enter the amount of substance (moles) and the molar mass (g/mole) into the Mass From Moles Calculator. The calculator will evaluate and display the Mass From Moles. 

Mass From Moles Formula

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

m = n * MM

  • Where m is the Mass From Moles (g)
  • n is the amount of substance (moles) 
  • MM is the molar mass (g/mole) 

How to Calculate Mass From Moles?

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

Example Problem #1:

  1. First, determine the amount of substance (moles). 
    • The amount of substance (moles) is given as: 1.60.
  2. Next, determine the mass molarity (g/mole). 
    • The mass molarity (g/mole) is provided as: 275.
  3. Finally, calculate the Mass From Moles using the equation above: 

m = n * MM

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

m = 1.60 * 275 = 440 (g)


Example Problem #2: 

For this problem, the variables needed are provided below:

amount of substance (moles) = 5

mass molarity (g/mole) = 125

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

m = n * MM = ?
