Problem
Assume that a single cylinder of an automobile engine has a volume of 524 cm2.

Part A
If the cylinder is full of air at 72 °C and 0.990 atm, how many moles of O2 are present? (The mole fraction of O2 in dry is 0.2095)

Part B
How many grams of C8 H18 could be combusted by this quantity of O2, assuming combustion with formation of CO2 and H2O?
