What is the mass of La2(C2O4)3*9H2O, can be obtained from 650mL of 0.0170 M aq solution of LaCl3 by adding a stoichiometric amount of sodium oxalate.

I don't know how to balance the equation for this..i started:

LaCl3+ Na2C2O4 -> La2(C2O4)3*9H2O + NaCl

  • Chemistry - ,

    You need to show the 9H2O on the LHS, from then on balancing it should be straight forwward. Balance the La atoms on the LHS then balance the Cl atoms on the RHS. Then balance the Na atoms on the LHS and you should find the oxalates will then already balance.
