How do you find the percent of a mixture?
It is calculated as the mass of the component divided by the total mass of the mixture and then multiplied by 100 to get the percent. Usually, mass is expressed in grams, but any unit of measure is acceptable as long as you use the same units for both the component or solute mass and the total or solution mass.
