The solubility of PbSO4 is 0.048g/1iter. What is the Ksp of PbSO4? (MM PbSO4 = 303.3)

Answer 1

0.048 g/L PbSO4/ 303.3 g/mol = 1.58E-4 mol/L
Then PbSO4 ---> Pb^2+ + [SO4]^2-
...........solid...........1,58E-4....1.58E-4
Ksp = (Pb^2+)(SO4^2-)
Plug in the solubility shown and turn the crank for value of Ksp. Check my arithmetic.
