Sodium metal reacts with water to produce hydrogen gas according to the following equation: 2Na(s) + 2H2O(l)2NaOH(aq) + H2(g) The product gas, H2, is collected over water at a temperature of 20 °C and a pressure of 753 mm Hg. If the wet H2 gas formed occupies a volume of 5.60 L, the number of moles of Na reacted was ____ mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
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.
A piece of sodium metal reacts completely with water as follows. 2 Na(s) + 2 H2O(l) 2 NaOH(aq) + H2(g) The hydrogen gas generated is collected over water at 25.0°C. The volume of the gas is 475 mL measured at 1.00 atm. Calculate the number of grams of sodium used in the reaction. (Vapor pressure of water at 25°C = 0.0313 atm.)
