3Pb (NO3) 2 + 2AlCl3 - - > 3PbCl2 + 2Al (NO3) 2

Look at the equation and concentrate on the mentioned compounds coefficients. So the coefficient of AlCl3 is 2 and the coefficient of PbCl2 is 3. These coefficients become the ratio of moles while calculating the number of moles produced. So by using the logic that 2 moles of AlCl is giving 3 moles of PbCl2, 14 moles of consumed AlCl gives (14/2) x 3 moles of PbCl2. That is 21 moles
