The theoretical mass of sulfur dioxide produced from 2.0 moles of sulfuric acid is ________. H₂SO₄ + Cu → SO₂ + H₂O + CuSO₄

Question

Quizplus · Accepted Answer

The balanced chemical equation shows that 1 mole of H₂SO₄ produces 1 mole of SO₂. Therefore, 2.0 moles of H₂SO₄ will produce 2.0 moles of SO₂. The molar mass of SO₂ is approximately 64.1 g/mol, so 2.0 moles of SO₂ will have a mass of 2.0 x 64.1 g/mol = 128.2 g. However, since the question asks for the theoretical mass of sulfur dioxide produced from 2.0 moles of sulfuric acid, the correct answer is 64.1 g for 1 mole.
