Collecting Gas over Water
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 756 mm Hg. If the wet H2 gas formed occupies a volume of 5.83 L, the number of moles of Al reacted was mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.

Collecting Gas over water
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 25 °C and a pressure of 746 mm Hg. If the wet H2 gas formed occupies a volume of 7.28 L, the number of grams of H, formed is g. The vapor pressure of water is 23.8 mm Hg at 25 °C.
