What is the maximum mass of the lower molar mass product that can be formed when 71.0 g of solid barium bromide and 44.5 g chlorine gas react?

Answer 1

BaBr2 + Cl2 ==> BaCl2 + Br2

This is a limiting reagent problem. I know that because BOTH reactants are given. I work these problems by solving two simple stoichiometry problems (simple meaning they are not limiting reagent problems and that usually gives you two answers for the product. The correct answer, in limiting reagent problems, is ALWAYS the smaller value and the reagent producing that number is the limiting reagent. Here is a link that will show you how to do the stoichiometry problems.
