Chemistry Question to do with the preparation of ammonia gas???

Ok this is a question I think I have right but amn't sure . . . please help!! :-)
When preparing ammonium gas from ammonium chloride and sodium hydroxide:
NH4Cl + NaOH = NH3 + NaCl + H2O (excuse the lack of subscript!!)
If 10.7g ammonium chloride and 10g sodium hydroxide are used, show that the sodium hydroxide is present in excess. Calculate the mass of sodium chloride and the volume of ammonia (measured at s.t.p.) formed.
