Answer to Question #336705 in General Chemistry for Pimp

Question

How many grams of water can be made when 17.5 moles of HNO3 are consumed

Answer 1

S + 6HNO₃ = H₂SO₄ + 6NO₂ + 2H₂O

m(H₂O) = (m(HNO₃) * 2Mr(H₂O)) / 6Mr(HNO₃)

m(HNO₃) = n(HNO₃) * Mr(HNO₃)

m(HNO₃) = 17.5 mol * 63.01 g/mol = 1102.68 g

m(H₂O) = (1102.68 g * (2*18 g/mol)) / 6 * 63.01 g/mol = 105 g
