In order for AlCl3 to somehow be converted to PbCl2, there must be a chemical reaction in which AlCl3 and some lead salt, for example PbCl2 react. There could be other possible reactions, but since the original question did not state a specific reaction, nor did it state specific conditions, the following will be assumed:
3Pb(NO3)2(aq) + 2AlCl3(aq( ==> 3PbCl2(s) + 2Al(NO3)3(aq) ... balanced equation
Using dimensional analysis and the mole ratios from the balanced equation, we can calculate moles of PbCl2 formed from 14 moles of AlCl3...
14 moles AlCl3 x 3 moles PbCl2/2 moles AlCl3 = 21 moles of PbCl2 formed
