A-level chemistry chemical reactions questions

I am finding this question really hard so hoping you could answer this for me,

1) The Haber process is the reaction between nitrogen and hydrogen to produce ammonia. I start off in the lab with 0.5g of nitrogen.
c) How many moles of ammonia would i produce if the reaction went to completion with excess hydrogen?
d) Industrially, the conditions the reaction is performed in should produce a 40% yield of ammonia. How many grams of ammonia would i produce in the lab for my experiment?

I would be really grateful if anyone helps me with any of these questions.
Thanks!

1. Write the balanced equation
2. Find the number of moles of Nitrogen
3. Multiply by the molar ratio of Ammonia to find the moles

4. Find the number of grams of Ammonia produced
5. Find the 40% of the grams
Moles = Mass / Mr for nitrogen
Write the balanced equation to find the ratio of moles

Work out mass using Mass = Moles X Mr
