The mass percentage of CaCO 3 in the given sample of compound should be determined. Concept introduction: For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass. Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal. The molar mass of an element or compound is the mass in grams of 1 mole of that substance, and it is expressed in the unit of grams per mol (g/mol). Mass percentage of reacted mass in the original sample is the ratio of mass of substance reacted to mass of whole sample taken. Mass percent of elements of a compound is the ratio of mass of element to the mass of whole compound and multiplied with hundred.
