Great! I haven't learn anything about Solubility Product before, it does not appear in my textbook either! However, this is what I hope to learn from brilliant users. So, I went searching some information about solubility product and solved this problem.

$\text{Solubility Product}=2.25\times10^{-8}$

$[Pb^{2+}][SO_4^{2-}]=2.25\times10^{-8}$

As the amount of $Pb^{2+}$ is equal with $SO_4^{2-}$ ,

$[Pb^{2+}]^2=2.25\times10^{-8}$

$[Pb^{2+}]=1.5\times10^{-4} mol/L$

The molecular mass of $PbSO_4=207+32+4\times16=303$

The solubility of the salt is,

$1.5\times10^-4 mol/L\times303g/mol=0.04545g/L$

I hope Gabriel can write a note about solubility product for other users who are not familiar with this concept. By the way, why use my name as the title of your problem!?
