Molar Mass: Found by adding together the molar masses of all of its elements.
Empirical Formula: Contains the smallest set of whole-number subscripts that give relative amounts of constituent atoms.
Molecular Formula: A chemical formula that gives the exact number of different atoms of an element in a molecule.
Law of Conservation of Mass: In every chemical operation an equal quantity of matter exists before and after the operation.
Stoichiometry: Is the use of chemical equations to calculate quantities of substances that take part in chemical reactions.
Stoichiometry Quantities: The exact amounts of reactants and products predicted by the balanced equations.
Limiting Reactant: Is the reactant that runs out first, based on the stoichiometric ratio of all the reactants.
Actual Yield: The amount actually obtained.
Percent Yield: The percentage of the theoretical amount that is actually obtained:
Combustion Analysis: A weighted sample of a compound is burned in a stream of oxygen gas; after combustion, all the carbon atoms in the sample are found in the and all the H atoms are in the .
