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 145.8 mL, the gas pressure sensors reads 101.7 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.

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:
Q1a-> A sample of hydrogen (H₂) gas was collected over water at 60°C. If the total volume of gas collected was 53.9 mL and the atmospheric pressure was 1.14 bar, what mass (in g) of hydrogen gas was collected above the water? The vapour pressure of water at 60°C is 150 torr. Q1b=> What is the molar mass (in g mol-¹) of a gas which has a density of 1.91 g/L at a pressure of 0.91 bar and temperature 15.3°C? Your answer may not correspond to an actual gas. Do not try to identify the gas.
