Chemistry concentration question

[From: ] [author: ] [Date: 12-04-16] [Hit: ]
The concentration of Pb, then,(10 ml/20 ml) * 0.010 M = 0.If there is a volume to the added water, then the total volume is substituted into the above equation where the 20 ml is now.......
I need to find the concentration Pb 2+ of the mixed solutions:
-10ml of 0.010M Pb(NO3)3
-0ml of water
-10ml of 0.020M of KI

Please help :)

Do you really mean 0 mL of water?

If yes, then add the two volumes together 10 ml + 10 ml is 20 ml, so you have doubled the total volume. The concentration of Pb, then, is cut in half:

(10 ml/20 ml) * 0.010 M = 0.0050 M [Pb+2]

If there is a volume to the added water, then the total volume is substituted into the above equation where the 20 ml is now.
