Homework Help: Chemistry- urgent!

Posted by Gabby on Thursday, December 15, 2011 at 11:45pm.

When a solution of sodium oxalate (Na2C2O4) is added to a solution of lanthanum (III) chloride, lanthanum oxalate (molar mass 541.86 g/mol) The balanced net ionic equation for the reaction is:
3C2O4^2- (aq) + 2La^3+ (aq) --> La2(C2O4)3 (s)

Thirty ml of 0.2000 M sodium oxalate are added to 25.00 ml of 0.1500 M La Cl3.

1) How many grams of La2(C2O4)3 (s) are obtained, assuming 100% yeild?

2) What are the concentrations (M) of La^3+, C2O4^2-, Na^+, and Cl^- after the reaction is complete? (Assume that the volumes are additive.)

Please help! Number one makes some sense but I don't understand 2 at all!
