How to Calculate Mass Percent: 13 Steps (with Pictures) - wikiHow

Now that the equation is filled in, simply solve to calculate the mass percent. Divide the mass of the element by the total mass of the compound and multiply by 100. This will give you the mass percent of the element. Example 1: mass percent = (2.01588/18.01528) x 100 = 0.11189 x 100 = 11.18%.
