PbCl₂ can be synthesized from Pb(NO₃)₂ using various reagents. I will be using HCl as follow,

Pb(NO₃)₂ + 2 HCl   → PbCl₂ + 2 HNO₃

According to equation,

   1 mole of PbCl₂ is formed by = 1 mole of Pb(NO₃)₂
So,
8 moles of PbCl₂ will be produced by = X moles of Pb(NO₃)₂

Solving for X,
X = (8 mol × 1 mol) ÷ 1 mol

X = 8 mol of Pb(NO₃)₂
Result:
  8 mol of Pb(NO₃)₂ are required to produce 8 moles of PbCl₂.
