The answer would be the Chemical formula for ammonia by hydrogen and nitrogen gas: 1 N2 + 3 H2 --> 2 NH3 then use stoichiometry. You know you have enough nitrogen gas to react, so you can just straight convert mol H2 to mol NH3, where 3 mol H2 = 2 mol NH3. 
3.44 mol H2 * (2 mol NH3 / 3 mol H2) = 2.29 mol NH3
