Theoritical amount of Sodium Bicarbonate

I have to find the theoretical amount of sodium bicarbonate. The steps I followed in order to produce it are:


1. 15g $\ce{NaCl}$ are added to a beaker. Then we add 87.5 mL of $\ce{NH3}(12M)$
2. We add 115g of dry ice(whose density is 1.5 g/mL)
3. Then the solid is taken with filtration and we rinse it first with 9mL of cold water and then with 6mL of acetone.


Then we put the solid in the oven. I know that the product after we take it off the oven will be sodium bicarbonate.
I believe that in order to find the theoretical amount of sodium bicarbonate I have to write down the reactions that are taking place.


$\ce{NaCl + NH\_3 + CO\_2 + H\_2O → NH\_4Cl + NaHCO\_3}$


But I'm confused as to if there is another reaction where $\ce{NH\_4Cl}$ and $\ce{NaHCO\_3}$ react with water or acetone. Also, working with the stoichiometry of the reactions, from which reactant is it better to conclude about the moles of NaHCO3?
