3) A small portion of gaseous gasoline (boiling point of gasoline: ~185 oF, it becomes gas at 212 oF) was then injected to mix with air in the container described in Question 2, according to air/fuel ratio (14.7:1 by mass). Consider 90% mass of gasoline is isooctane and the rest is ethanol (C2H6O), how much are isooctane and ethanol in moles added, respectively? With the amount of gasoline injected, what is new total pressure of the container? (Mass of air = 0.892 g, Volume of container = 1.00 L, presure of air = 1.00 atm) 4) In “the intake stroke”, the air/C8H18 gaseous mixture in Question 3 is transferred into the cylinder, where the piston reaches the bottom of the cylinder. Assume the gas mixture an ideal gas behavior, the temperature of cylinder is 212 oF, and the total pressure of gas mixture is 1.00 atm, Calculate moles of C8H18, O2 and the total moles of air/fuel mixture.
