Your answer should have three significant figures.
A steel cylinder contains 5.00 moles graphite (pure carbon) and 5.00 moles O2. The mixture is ignited and all the graphite reacts. Combustion produces a mixture of CO gas and CO2 gas. After the cylinder has cooled to its original temperature, it is found that the pressure of the cylinder has increased by 25.0%. Calculate the mole fractions of CO, CO2, and O2 in the final gaseous mixture.
Mole fraction of CO =
