Document Summary
The upcoming midterm exam next wednesday is cumulative. Anything we covered in class, problem sets and handouts, from day one up to and including the lecture before the exam, can be on it. The following were pumped into a 5. 00 l tank at 25 c: 46 l of o2 (g) at 1. 00 atm. 12 l of he (g) at 2. 00 atm. Calculate the partial pressures of o2 and he, the total pressure and the mole fractions of o2 and he. The two gases don"t react and therefore for each gas, n and t are constant. Ptotal = 9. 2 + 4. 8 = 14. 0 atm. Xhe = 1 xo2 = 1 0. 66 = 0. 34 = Total pressure = pressure of collected gas + pressure of water vapor above the water liquid. The pressure of water vapor above liquid depends only on the temperature and is called saturated vapor pressure (svp) at the temperature of the experiment.
