Question 2 (0.5 marks) Hydrogen gas, H2, and oxygen gas, O2, can be reacted to form liquid water. If 2.00 Rhydrogen gas and 17.20 g oxygen gas are reacted in a 1.500 L flask at 25.0°C, calculate the total gas pressure (atm) in the flask at 25 °C. The vapor pressure of water is 23.8 mm Hg. Stoichiometry is involved in this question. Total gas pressure:
