What have done so far. I showed you how to convert mols Na2CO3 to mols NiCO3.
You convert mols NiCl2 to mols NiCO3 the same way, then take the smaller of the two mols as the correct one.
A solution containing 0.100 mol of Na2CO3 and 0.100 mol of NiCl2 is allowed to react. What mass of precipitate forms in this reaction?

So it would be NiCl2 right?
