Enter the mole percent (%), the number of moles of all substances, and the molar weight (g/mol) into the Mole Percent to Weight Calculator. The calculator will evaluate the Mole Percent to Weight. 

Mole Percent to Weight Formula

The following formula is used to calculate the Mole Percent to Weight. 

W = MP/100 * #n * MW

Variables:

  • W is the Mole Percent to Weight (g)
  • MP is the mole percent (%) 
  • #n is the number of moles of all substances 
  • MW is the molar weight (g/mol) 

How to Calculate Mole Percent to Weight?

The following steps outline how to calculate the Mole Percent to Weight.


  1. First, determine the mole percent (%).
  2. Next, determine the number of moles of all substances. 
  3. Next, determine the molar weight (g/mol). 
  4. Next, gather the formula from above = W = MP/100 * #n * MW.
  5. Finally, calculate the Mole Percent to Weight.
  6. 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.

mole percent (%) = 25

number of moles of all substances = 500

molar weight (g/mol) = 30

W = MP/100 * #n * MW =  ?
