A small amount of gaseous gasoline is added into a container to mix with air (air is at 212 F). The air to fuel ratio is 14.7:1 by mass. Note that the boiling point of gasoline is ~185 F, and it becomes gas at 212 F. 90% of the mass of gasoline is isooctane and the remaining is ethanol (C2H6O). How much of isooctane and ethanol in moles has been added to the container? With the amount of gasoline added, what is the new total pressure of the container?
Note: The container has a volume of 1.00 L, the pressure of air in the container is 1.00 atm and has a molecular composition of 79% N2 and 21% O2.
moles of O2 in the container = 0.006846 mol
moles N2 in the container = 0.025754 mol
The mass of air = 0.939 g

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(total mass of air=.892) , 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?

A gaseous stream containing 20.0 mole% ethanol and 80.0 mole% air is to be cooled from 60.0°C to 9.65°C in a condenser at the constant pressure of 1 atm to liquefy some of the ethanol. The gas stream entering the condenser has a pressure of 1.00 atm, flows at a rate of 10.0 mole/s and, at 60°C, is well above the saturation temperature (42.4°C). As a result of the cooling, 1.75 mole/s of liquid ethanol (Tbp = 78.5°C) leaves the...
