**chemistry**

my teacher insists that we do it that way, i don't really understand it but i try! so it would come out to be 0.026 moles Pb(NO3)2. Then, converting Pb(NO3)2 into KCl it would come out to be 0.052 Moles KCl. Then divide 0.052 by 0.150 which would equal 0.15 L?

**chemistry**

okay so the solution would be. 0.150 M KCl x 0.175 M Pb(NO3)2/ 1 M KCL x 0.150 L/0.175 M Pb(NO3)2 = 0.023 L?

**chemistry**
