Phosphoric acid (H3,PO4) is a key ingredient in soft drinks that gives it a

sharper flavor. One way to produce this acid is with the aid of mineral

fluoroapatite (Ca5(PO4)3F) following this reaction:

Ca5(PO4)3F + 5H2SO4 → 3H3PO4 + 5CaSO4 + HF

If 24.5 g Ca5(PO4)3F is mixed with 89.7 g H2SO4

, how much H3PO4 will form?
