Table 1. Vapor Pressure of Water at Different lem Temperature, °C PH3Os mm Hg Temperature, C PHo, mm Hg 16°C 13.6 22 °C 19.8 17°C 14.5 23 °C 21.1 18°C 15.5 24 °C 22.4 19 °C 16.5 25 °C 23.8 20 °C 17.5 26 °C 25.2 21 °C 18.7 27 °C 26.7 A reaction of 0.028 g of magnesium with excess hydrochloric acid generated 31.0 mL of hydrogen gas was collected by water displacement in a 22 °C water bath. The barometric pressure gas. The in the lab that day was 746 mm Hg. 1. Use Dalton's law and the vapor pressure of water at 22 °C (Table 1) to calculate the partial pressure of hydrogen gas in the gas collecting tube. 2. Use the combined gas law to calculate the "corrected" volume of hydrogen at STP. Hint: Watch your units for temperature and pressure! 3. What is the theoretical number of moles of hydrogen that can be produced from 0.028 g of Mg? Hint: Refer to Equation I for the balanced equation for the reaction. 4. Divide the corrected volume of hydrogen by the theoretical number of moles of hydrogen to calculate the molar volume (in L/mol) of hydrogen at STP.
