Sodium metal reacts with water to produce hydrogen gas according to the following equation: 2Na(s) + 2H20(1)2NAOH(aq) + H2(g) The product gas, H2, is collected over water at a temperature of 20 °C and a pressure of 744 mm Hg. If the wet H2 gas formed occupies a volume of 9.27 L, the number of moles of Na reacted was mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
