The Mass Percent of a solution is equal to the grams of solute per 100 grams of solution. The formula is:

Mass Percent = ((mass of solute) / (mass of solution)) x 100%

This equation may be rearranged to solve for any one of those three variables. The mass may be in any mass units as long as the mass units are consistent with each other. It is also useful to realize that the density of water is approximately 1 g/mL, so volumes of water in mL are equal to masses in grams.

In this video, I also describe how to make a solution of a certain mass percent.
