Enter the average molar mass (g/mole) and the total moles of the compound into the Compound Mass Calculator. The calculator will evaluate and display the Compound Mass. 

Compound Mass Formula

The following formula is used to calculate the Compound Mass. 

CM  = AMM * N
  • Where CM is the Compound Mass (g)
  • AMM is the average molar mass (g/mole) 
  • N is the total moles of the compound 

To calculate the compound mass, multiply the average molar mass by the number of moles of compound.

How to Calculate Compound Mass?

The following example problems outline how to calculate Compound Mass.

Example Problem #1:

  1. First, determine the average molar mass (g/mole).
    • The average molar mass (g/mole) is given as: 35.
  2. Next, determine the total moles of the compound.
    • The total moles of the compound is provided as: 6.
  3. Finally, calculate the Compound Mass using the equation above: 

CM  = AMM * N

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

CM  = 35 * 6 = 210 (g)

Example Problem #2: 

For this problem, the variables needed are provided below:

average molar mass (g/mole) = 75

total moles of the compound = 6

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

CM  = AMM * N = ?
