Consider two reactants (A and B) that when mixed form a precipitate C, which can be filtered, dried, and then weighed. Carlos attempts to find the stoichiometric ratios in which A and B mix, by mixing different volumes of the same concentration of solutions of A and B (0.50 M). He records the following data: Run Vol A (mL) Vol B (mL) Mass C (g)1 10.0 10.0 1.172 20.0 10.0 2.33 3 30.0 10.0 3.504 40.0 10.0 3.50 Which of the compounds (A or B) is the limiting reagent? Run Limiting Reagent 1 2 3 4What is the stoichiometric ratio in which A and B combine?
