A balanced chemical equation can be read like a recipe - a recipe that describes the amounts of ingredients (reactant chemicals) that must be mixed together in order to produce a specific quantity of baked goods (product chemicals). The ingredients - reactant chemicals - are identified by their chemical formulas. The same is true of the baked goods (product chemicals). The coefficients in the balanced chemical equation describe the amounts of reactants and products. The unit mole is the most common unit used to describe these amounts. If the amount of a reactant or product is desired in the unit grams, then a molar mass value must be used to conduct such a conversion.

You can think of this difficulty level as involving five problems. Each row is a problem. And each row is independent of any other row. That is, for Row B, all you need to know is Row B information in order to determine the blanks in Row B. Success with this question is dependent upon your understanding of and ability to use the coefficients in the balanced chemical equation and your ability to use molar mass values to convert from moles to grams. The graphics below should help you with your understanding. The sections titled Mole to Mole Conversions and Mole to Gram Conversions and Gram to Mole Conversions will be particularly helpful.
