Answer:
Determine the limiting reagent
Using the stoichiometric ratios from the balanced reaction equation the mole ratio of Na : NaCl = 2 : 2.
The moles of NaCl produced by 15 moles of Na can be obtained as follows.

, Na is the limiting reagent.
The theoretical yield of NaCl = Moles of NaCl produced by the limiting reagent =
