(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What molar concentration of each ion appear in 0.16M Pb(NO_{3})_{2}?

*Note* The title incorrectly says "moles".

2. Relevant equations

M = mol/L

3. The attempt at a solution

My teacher tells me this is wrong, but I can't see my fault:

Molar Mass of Pb^{+2}= 207.20g

Molar Mass of NO_{3}^{-}= 124.02g

[itex]\frac{x}{1L} = 0.16M[/itex]

[itex]x = 0.16mol[/itex]

[itex]0.16mol = \frac{y*1mol}{331.22g}[/itex]

[itex]y = 53g[/itex]

[itex]Pb: 53g * \frac{207.20g}{331.22g} = 33g[/itex]

[itex]\frac{33g}{331.22g} = 0.10mol[/itex]

[itex]NO_{3}: 53g *\frac{124.02}{331.22g} = 20g[/itex]

[itex]\frac{20g}{331.22g} = 0.06mol[/itex]

[itex]Pb = \frac{0.10mol}{1L} = 0.10M[/itex]

[itex]NO_{3} = \frac{0.06mol}{1L} = 0.06M[/itex]

Any ideas where I messed up?

Or if I did?
