Mass percent is the percentage of each element in a chemical compound. To find the mass percent, you need the molar mass of the element in the compound in grams/mol, or the mass in grams used to make the solution. The mass percent can be calculated easily using the basic formula by dividing the mass of the element (or solute) by the mass of the compound (or solution).
