How to Calculate Mass Percent 13 Steps (with Pictures

Mar 29, 20190183;32;Mass percent tells you the percentage of each element that makes up a chemical compound. Finding the mass percent requires the molar mass of the elements in the compound in grams/mole or the number of grams used to make a solution. It is simply calculated using a basic formula dividing the mass of the element (or solute) by the mass of the compound (or solution).
