AP Chemistry
4.7 Types of Chemical Reactions
4.5 Stoichiometry
A student evaluates a system that condenses water produced by a small fuel burner. The student burns a \(22.8\text{ g}\) sample of pure octane, \(\text{C}_8\text{H}_{18}\text{(l)}\), in excess oxygen according to the equation
\[2\text{C}_8\text{H}_{18}\text{(l)}+25\text{O}_2\text{(g)}\rightarrow16\text{CO}_2\text{(g)}+18\text{H}_2\text{O(g)}\]
Assuming complete combustion and complete collection of the condensed water, what mass of water is collected?
