. Percent Composition:The percentage of amount of a certain element or component in a compound in comparison to the molar mass of the compound is known as the percent composition of that substance in the compound.Answer and Explanation:
Mass percentcomposition (also called mass percent or percent composition) is the easiest way to express the concentration of a solution because no unit conversions are required. Simply use a scale to measure the mass of the solute and the final solution and express the ratio as a percentage. ...
