A piece of Na metal undergoes a complete reaction with H2O (l0 to produce sodium hydroxide and hydrogen. If 24.0 g of Na in a 3.50 L container is reacted with an excess amount of water at 25 degrees Celsius, calculate the total pressure (in atm) in the 3.50 L container when the reaction is completed. (The vapor pressure of H2O at 25 degrees Celsius = 23.8 mm Hg)
