Answer to Question #322629 in General Chemistry for thea

Question

1.             What mass of calcium sulfate can be produced from the reaction of 1250 g calcium phosphate with 750 g H₂SO₄?

 

Ca₃(PO₄) ₂ (s) +  H₂SO₄(aq) à   CaSO₄(s) + H₃PO₄(aq)

Give the given, unknown and full solution.

Answer 1

Moles= mass/ rfm

Moles of calcium phosphate = 1250/310= 4moles

Moles of H2SO4= 750/98= 7.7moles

Mole ratio= 1:1

Mass of calcium sulfate= 4× 136= 544g
