Question:

A 0.608-g sample of fertilizer contained nitrogen as ammonium sulfate, (NH4)2SO4. It was analyzed for nitrogen by heating with sodium hydroxide.
(NH4)2SO4(s) + 2NaOH(aq) → Na2SO4(aq) + 2H2O(l ) + 2NH3(g)
The ammonia was collected in 46.3 mL of 0.213 M HCl (hydrochloric acid), with which it reacted.
NH3(g) + HCl(aq) → NH4Cl(aq)
