Question

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

Joaquin needs to react [m] grams of calcium phosphate. He will need to measure out ____ grams H2SO4 for this reaction.

Answer 1

The answer to your question is below

Step-by-step 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
