hello, i know part a but i need help with part b and c

1a) For the following questions, identify the ions comprising the salt, and then use the expression for the solubility product to perform the necessary calculations. This simple exercise involves the assumptions that you can ignore any complications which might result as a consequence of the basicity or acidity of the ions, ion pairing, complex ion formation, or auto-ionization of water.

 

Calculate the concentration, in mol/L, of a saturated aqueous solution of PbSO4 (Ksp = 1.30×10-8). The answer to this is 1.14×10-4 mol/L

1b) Calculate the solubility, in g/100mL, of PbSO4.

1c) Calculate the mass of Ag3PO4 (Ksp = 1.80×10-18) which will dissolve in 100 ml of water.
