gramsmole Its essential for converting between mass and moles a critical step in stoichiometric calculations Example The molar mass of water HO is approximately 1802 gmol calculated by adding the atomic masses of hydrogen and oxygen This allows conversion between mass and the number of moles of water Limiting Reactants Identifying the Bottleneck In many reactions one reactant is used up before others This limiting reactant dictates the maximum amount of product that can be formed Identifying the limiting reactant is crucial for accurate stoichiometric calculations Example Imagine making sandwiches products You have 5 slices of bread reactant A and 3 slices of meat reactant B The recipe calls for 2 slices of bread and 1 slice of meat per sandwich Meat is the limiting reactant as you can only make 3 sandwiches Percent Yield Evaluating Reaction Efficiency Percent yield measures the efficiency of a chemical reaction by comparing the actual yield what you get to the theoretical yield what you expect based on stoichiometry Example A chemist plans to synthesize aspirin CHO based on the reaction involving salicylic acid If the theoretical yield is 15 grams of aspirin but the actual
