Question

Ammonium sulfate can be made by the reaction H2SO4 + 2 NH3 ® (NH4)2SO4. What quantity of ammonium sulfate will result from the reaction of 5.00 kg of ammonia and 20.0 kg of sulfuric acid?

Answer 1

This is a limiting reagent problem; I know that because the problem gives BOTH reactants. I solve these by solving two simple stoichiometry problems (simple meaning they are not limiting). Here is a solved example. Just follow the steps. Determine moles of one of the products using the first reactant; follow the same procedure for the second reactant. In limiting reagent problems, the SMALLER number is ALWAYS the correct one to use.
