Assume that a single cylinder of an automobile engine hasa volume of 524 cm3. (a) If the cylinder is full of air at 74 °C and 0.980 atm, how many moles of O2 are present? (Themole fraction of O2 in dry air is 0.2095.) (b) How manygrams of C8H18 could be combusted by this quantity ofO2, assuming complete combustion with formation ofCO2 and H2O?

a) Since PV = nRT where P = pressure in atm = 0.98 V = volume in lit = 524 / 1000 = 0.524 T =…
