Enter the total number of moles and the total mass (grams) into the Calculator. The calculator will evaluate the Moles Per Gram. 

Moles Per Gram Formula

m:g = m/w


  • m:g is the Moles Per Gram (moles/gram)
  • m is the total number of moles
  • w is the total mass (grams)

To calculate Moles Per Gram, divide the number of moles by the mass in grams.

How to Calculate Moles Per Gram?

The following steps outline how to calculate the Moles Per Gram.

  1. First, determine the total number of moles. 
  2. Next, determine the total weight (grams). 
  3. Next, gather the formula from above = m:g = m/w.
  4. Finally, calculate the Moles Per Gram.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total number of moles = 30

total weight (grams) = 50
