1.4 g
*convert g to mol*
Pb=207.2 amu (Atomic Mass)
Cl=35.453 amu (atomic mass)
since it's PbCl2, 207.2 + 35.453 + 35.453=278.106
1.4/278.106=.005 mol
*use Avogadro's number to find formula units*
.005 x 6.02E10^23 --> 3.03E10^22 formula units PbCl2

How many moles of PbCl₂ are produced if 14 moles of AlCl₃ are consumed?
Using the balanced equation 2 AlCl₃ + 3 Pb(NO₃)₂ → 3 PbCl₂ + 2 Al(NO₃)₃, the mole ratio between AlCl₃ and PbCl₂ is 2:3. Therefore, if 14 moles of AlCl₃ are consumed, 9.33 moles (14 moles / 2 * 3) of PbCl₂ will be produced.
