what mass of H2O can be produced?

Question

Given the equation below, 12.35 grams of H₂SO₄, and excess Ca(OH)₂, what mass of H₂O can be produced? Round your answer to two digits after the decimal point.

H₂SO₄ + Ca(OH)₂ à 2 H₂O + CaSO₄

Answer 1

H₂SO₄ + Ca(OH)₂ ==> 2 H₂O + CaSO₄ .. balanced equation

moles H₂SO₄ present = 12.35 g H₂SO₄ x 1 mol H₂SO₄ / 98.08 g = 0.12592 moles

mass H2O produced = 0.12592 mols H₂SO₄ x 2 mol H2O / mol H₂SO₄ x 18.02 g H2O/ mol = 4.54 g H2O
