The stoichiometrically balanced equation for this is.....

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

Explanation:

Anyway you asked the mass of sodium reacted. This is simply #0.05*molxx22.99*g*mol^-1=1.15*g#.

Can you tell me (i) the volume of dihydrogen gas released given #298*K# temperatures, and #1*atm# pressures; and (ii) the #pH# of the resulting solution had it been diluted to #1*L#?

Enquiring minds want to know!
