| Abstract | Students determine the relative atomic masses of calcium, magnesium, and aluminum by reaction with hydrochloric acid and measurement of the volume of hydrogen gas liberated. The experiment demonstrates stoichiometry and illustrates clearly that mass of the reagent is not the determinant of the amounts in chemical reactions. The experiment is intended for students undertaking a first course in introductory chemistry. (Contains 1 table and 2 notes.) (As Provided). |
