Answer to Question #174600 in General Chemistry for Danielle

Question

Pure carbon reacts with sulfur dioxide gas producing liquid carbon disulfide and carbon monoxide gas. How many liters of carbon monoxide will be produced if 40.0 grams of sulfur dioxide are allowed to react with excess carbon

Answer 1

The balanced reaction equation:

5C + 2SO₂ = CS₂ + 4CO

Molecular weight of SO₂ is 64 g/mol

The quantity of SO₂ is 40 g / (64 g/mol) = 0.625 mol

The quantity of CO is 2 * 0.625 mol = 1.25 mol

The volume of CO is 1.25 mol * (22.4 l/mol) = 28 liters

Answer: 28 litres
