Mass percent tells you the percentage of each element that makes up a chemical compound. [1] 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. [2] It is simply calculated using a basic formula dividing the ...

en.wikipedia.org/wiki/Mass_fraction_(chemistry)

In chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. Expressed as a formula, the mass fraction is: =. Because the individual masses of the ingredients of a mixture sum to , their mass fractions sum to unity: ∑ = = Mass fraction can also be expressed, with a denominator of 100, as ...
