Jake, you missed it on the products. Nitrates are soluble, but lead phosphate is not. Mg3(PO4)2 + 3Pb(NO3)2 --> 3Mg(NO3)2 (aq) + Pb3(PO4)2 (s) So the net ionic equation is... 2PO4-- + 3Pb++ >> Pb3(PO4)2 (s)

I've corrected the equation. 2H3PO4 +3Mg(OH)2 ==> Mg3(PO4)2 + 6H20 mols Mg(OH)2 = M x L = ? Convert mols Mg(OH)2 to mols H3PO4 using the coefficients in the balanced equation. Then mols H3PO4 = M H3PO4 x L H3PO4 You know mols and M, solve for L.

No. An equation is balanced only if mass is balanced AND charge is balanced. EQuation (2) balances both. Check the charge changes to verify.
