Question: The following equilibrium was studied by analyzing the equilibrium mixture for the amount of HCL produced. LaCl3(s)+ H2O(g) goes to LaOCl(s)+2HCl(g). A vessel whose volume was 1.25L was filled with 0.0125 mol of lanthanum (III)chloride and 0.0250 mol H2O. After the mixture came to equilibrium in the closed vessel at 619 degree C the gaseous mixture was removed and dissolved in more water sufficent silver (I)ion was added to precipitate the chloride ion completely as silver chloride. If 3.59g AgCl was obtained, what is the value of Kc at 619 degree C?

I worked out the problem could you please show me how you would work it so i can check my answer
