The mass of an empty Erlenmeyer flask and stopper was determined to be 55.83 grams. When filled with distilled water, the mass was 294.8 grams. The atmospheric pressure was measured to be0.9337 atm, the room temperature was 20.00oC. At this temperature, the vapor pressure of water is 17.50 torr -- but assume a 50% relative humidity as outlined in the procedure for this experiment.
A mixture of gases contains 0.290 mol CH4, 0.240 mol C2H6, and 0.300 mol C3H8. The total pressure is 1.40 atm. Calculate the partial pressure of the gases.
