Unformatted text preview: 2a. When determining the vapor pressure of water by the method of this experiment, the bubble volume at 5°C was found to be 1.2mL. How many moles of dry air were in the bubble? b. If the bubble volume is 8.6mL at 75°C, what is the partial pressure of the dry air, in torr, at this temperature?...
