EXAMPLE Calculate the volume of gaseous NO produced by the combustion of 100 g of NH at 0C and 100 kPa. Stoichiometry (/ s t k i m t r i /) is the relationship between the quantities of reactants and products before, during, and following chemical reactions.. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products . In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements. The worksheet has ten problems that give a balanced reaction and a starting amount of a reactant or product in, determine the mass of another reactant or product in each problem.
