Olympiad Chemistry: Mole Concept and Stoichiometry
Twenty olympiad questions on the mole concept and stoichiometry: limiting reagent and percentage yield, formulae from analysis data, gas stoichiometry and mixtures of gases, molarity, molality and mole fraction, dilution, titration and back-titration, successive reactions, and equivalent and average molar mass. Most have one correct option; four ask for a number and three have one or more correct options. Every question has a hint and a full worked solution.
