If #"0.5 mol BaCl"_2"# reacts with #"0.2 mol Na"_3"PO"_4"#, what is the maximum amount of #"Ba"_3"(PO"_4)_2"# that can be produced?
The maximum amount of
This is a limiting reactant (reagent) question. The reactant that produces the least amount of barium phosphate is the limiting reactant. The limiting reactant determines the maximum amount of a product can be produced.
Start with a balanced equation.
Multiply the moles of each reactant times the mole ratio from the balanced equation with barium phosphate in the numerator to get moles of barium phosphate.
