You need to specify a mass of sodium metal.......

#Na(s) + H_2O(l) rarr NaOH(aq) + 1/2H_2(g)uarr#

Explanation:

If #1*g# of sodium metal were dropped into a beaker of water, along with spitz and sparx we would get......

#1/2xx(1*g)/(22.99*g*mol^-1)xx2.02*g*mol^-1=0.044*g# #"dihydrogen gas"#.

Of course, if we specify the temperature, and assume #1*atm# pressure, we could calculate the volume of dihydrogen gas produced.
