A piece of sodium metal reacts completely with water as
follows:
2Na(s) + 2H2O(l) à 2NaOH(aq) +
H2(g).
The hydrogen gas generated is collected over water at
25.0oC. The volume of the gas is 252mL measured at
1.00atm. Calculate the number of grams of sodium used in the
reaction. (Vapor pressure of water at 25oC =
0.0313atm).
