Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas according to the following equation: 2Al(s) + 2NaOH(aq) + 6H2O(1)>2NaAl(OH)4(aq) + 3H2(g) The product gas, H2, is collected over water at a temperature of 20 C and a pressure of 742 mm Hg. If the wet H2 gas formed occupies a volume of 5.38 L, the number of moles of Al reacted was | mol. The vapor pressure of water is 17.5 mm Hg at 20 C. Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas according to the following equation: 2Al(s) + 2NaOH(aq) + 6H20(1)>2NaAl(OH)4(aq) + 3H2(g) The product gas, H2, is collected over water at a temperature of 20 C and a pressure of 758 mm Hg. If the wet H2 gas formed occupies a volume of 5.22 L, the number of grams of H2 formed is | g. The vapor pressure of water is 17.5 mm Hg at 20 C
