I also need help with;
what is the concentration of;
1) lead ions in a 0.02M solution of lead nitrate
2) iron(III) ions in a solution of magnesium iodide where [NO3 -] =0.45M (- is minus 1)

$$The Ionic equation of Pb(NO_{3})_{2} \ is: Pb^{2+} + 2NO_{3}$
$Since the given molarity (concentration) is 0.02M\cdot L^{-1}$ \ $you simply have times the molarity with the molar ratio of the ionic equation$
$So the answer to the first question is 0.04M\cdot L^{-1}$

btw don't trust omed62, just read through his past posts and you'll know what i mean
