Question

Ca3(PO4)2 + 3 H2SO4 ⟶ 2 H3PO4 + 3 CaSO4

Answer 1

Answer:

The answer to your question is below

Explanation:

Balanced chemical reaction

               Ca₃(PO₄)₂  +  3H₂SO₄   ⇒   2H₃SO₄  +  3CaSO₄

To answer this question just calculate the molar mass of both reactants.

Molar mass of Ca₃(PO₄)₂ = (3 x 40) + (2 x 31) + (8 x 16)

                                         = 120 + 62 + 128

                                         = 310 g

Molar mass of 3H₂SO₄ = 3[(2 x 1) + (1 x 32) + (4 x 16)]

                                      = 3[2 + 32 + 64]

                                      = 3[98]

                                      = 294 g

Conclusion

310 g of Ca₃(PO₄)₂ will react with 294 g of 3H₂SO₄
