Sodium metal reacts with water to produce hydrogen gas: 2Na(s) + 2H2O(l)2NaOH(aq) + H2(g) In one experiment, a sample of Na reacts and the gas produced is collected by water displacement. The gas sample has a temperature of 22.00 °C, a volume of 869.0 mL, and a pressure of 742.0 mm Hg. Calculate the amount (in moles) of hydrogen gas produced in the reaction. The vapor pressure of water is 19.83 mm Hg at 22.00 °C.
