What is the theoretical yield of NaHCO3 in grams?

A weighted amount of NaCl is completely dissolved in measured Vol of 4.00 M NH3 solution at ice temp, and CO2 is bubbled in. Assume that NaHCO3 is formed until the limiting reagent is entirely used up. The solubility of NaHCO3 in water at ice temp is 0.75 mol/L. Also assume that all the NaHCO3 precipitated is collected and converted quantitatively to Na2CO3. GIVEN: Mass of NaCl : 14.7 g Vol of NH3 : 39.9 ml moles of Nacl : 0.251 moles of NH3: 0.160 Questions: 1 / What is the theoretical yield of NaHCO3 in grams? 2 / How many grams of NaHCO3 formed will precipitated from the above Vol of solution? 3 / How many grams of Na2CO3 will be produced from this precipitate? Please help me out on these I could answer first 3 question but then I stuck on these , I don't get it. Thank you already

This looks like either a GCSE or A-level standard question in chemisty.

These sorts of questions are quite standard but the good news is that they are also simple.

But you do need to learn how to do it yourself so that when one comes along in an exam you get the answer right.

There will be a worked example of this sort of question in your chemistry textbook so for best results work out the method from that then replicate here.
