  • Quantitative Chemistry
    • The relative formula mass is the sum of all relative atomic masses of atoms in formula
    • The emperical formula shows the ratio of each atom in the formula
    • percentage composition is the percentage of an element in a formula by mass
    • Balanced equations are used to calculate reacting masses
    • A yield is the amount of product made in a reaction
    • The theoretical yield is the calculated yield
    • The percentage yield is the actual yield divided by the calculated yield
    • Industrial chemists consider yields, waste and reaction rates when making products
    • Actual yield is nearly always less than the theoretical yield because not all reactants react, the reaction may be reversiable and other reactions may occur
