Question 26

Propane burns in oxygen to form carbon dioxide and water.

\text{C}_3\text{H}_8 + 5\text{O}_2 \rightarrow 3\text{CO}_2 + 4\text{H}_2\text{O}

Calculate the mass of carbon dioxide made when 22.0 g of propane is completely burnt. (Relative atomic masses: $H=1.0\text{H} = 1.0$ , $C=12.0\text{C} = 12.0$ , $O=16.0\text{O} = 16.0$ )
