Please help with theoretical yield? And how to solve it?

How many molecules of Mg3N2 (magnesium nitride) are formed when excess Mg (magnesium)
reacts with 24.3 moles of N2 (nitrogen gas)?
3Mg(s) + N2(g) → Mg3N2(s) 43.1 molecules Mg3N2

32.5grams of NaOH (sodium hydroxide) reacts an excess of CO2 (carbon dioxide).
2NaOH(s) + CO2(g) → Na2CO3(s) + H2O(l)

a. What is the theoretical yield of Na2CO3 in grams? 43.1g Na2CO3

b. If 16.45 g of Na2CO3 is formed, what is the percent yield? 38.2%
