I have this chemistry problem that I have been trying to answer since last week, but still I can't figure it out. Please help!
Petroleum based fuels like gasoline consist mainly of hydrocarbons, compounds containing only hydrogen and carbon. One of the compounds in gasoline is isooctane, C8H18. When burned in a car's engine, some isooctane conbusts completely to form carbon dioxide and water, as shown in equation (1), and some combusts incompletely to form carbon monoxide and water, as shown in equation (2).
(1) 2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O
(2) 2 C8H18 + 17 O2 --> 16 CO + 18 H2O
If 50.0 g of isooctane burns to produce 221.2 g of total gaseous products ( a mixture of CO2, CO, and H2O), determine the percent by mass of isooctane that reacts by complete combustion.
