In part 1 of this experiment you will be determining the enthalpy of vaporization of water. To do this you must first find the number of moles of air in your U-Tube measuring device. If you determine that the volume of air is 0.200 mL at 2.0 °C, when the barometric pressure in the room is 728.0 torr, then how many moles of air are in the U-tube? R= 6.237 x 104 mL torr mol-1-K-1 O a. 8.49 x 10-6 moles Ob.9.38 x 10-4 moles O c. 7.12 x 10-9 moles O d. 6.20 x 10-2 moles
