Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas according to the following equation: 2AI9) + 2NaOH(aq) + 6H,00)—2NaA{ОН), (aq) + 3H2(g) The product gas, H2, is collected over water at a temperature of 20 °C and a pressure of 741 mm Hg. If the wet H2 gas formed occupies a volume of 6.38 L, the number of moles of Al reacted was | |mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
