In this lab, you will start off by calculating the number of moles of air molecules inside a flask containing 20 mL of water by cooling the flask down to near 0°C and assuming the vapour pressure of water is negligible at that temperature. If the volume of the air inside the flask is 145.2 mL, the gas pressure sensors reads 101.3 kPa and the temperature sensor reads 3.7 °C, how many moles of air are present in the flask? Express your answer in mol. Assume R = 8.314 J mol-¹ K-¹. Answer:

4. The heat of vaporization of a liquid may be obtained from the approximated integrated form of the Clausius-Clappeyron equation In (P2/P,) 1/T,- 1/T, T,T2 T2 - T, P P2 AH, = -R- = R -In- For water, the vapor pressure is measured to be 9.2 Torr at 10.0°C (283.15K) and 55.3 Torr at 40.0°C (313.15K). Taking R to be 8.3145 JK' mol', calculate AHvap. Taking the limit of error (95% confidence) in the temperature measurement to be 0.1K and that in the pressure measurements to be 0.1 Torr, calculate the uncertainty in AHvap. A literature source gives 43,893 J/mol for AHvap at 25°C. Is the difference between this value and your value significant at the 95% confidence level?
