A kf1.amplifire.c SAM P Pearson Learning: Ch 03R: Chemical Reactions and Chemical Quantities QUESTION Stoichiometry is a term chemists use to describe calculations that determine the relative quantities of reactants or products involved in a chemical reaction. Using stoichiometry, chemists can determine the amount of product that can be formed during a chemical reaction from a given amount of reactant. Chemists can also determine the amount of reactant needed to produce a desired amount of product using the same process. Select the missing conversion factor for the following set of calculations. Assume 171 grams of diborane, B,H¸, reacts with excess oxygen, O̟. The problem requires that you determine the mass of boron oxide, B_O¸, formed from this reaction.
