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 420 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.)
