Question

Hydrogen chloride reacts with sodium sulfate. how many grams of hydrogen sulfate will be produced if you start with 20.0 grams of hydrogen chloride?

Answer 1

First write the balanced chemical reaction.

2 HCl + Na₂SO₄ → H₂SO₄ + 2 NaCl

20.0 g HCl x (1 mol HCl / 36.46 g HCl) x (1 mol H₂SO₄ / 2 mol HCl) x (98.08 g H₂SO₄ / 1 mol H₂SO₄) = 26.9 g H₂SO₄
