A titration of 50.00 ml of a solution containing iodide is titrated to a thiocyanate endpoint with 0.0683 M silver nitrate solution.  The initial buret reading was 1.26 ml.  At the first evidence of of the red endpoint the buret read 13.89 ml.  Find the concentration of the iodide in the original solution.  Express the final result also as percentage of calcium iodide in the solution. 

Here is my equation  CaI2 + 2AgNO3 = 2AgI + Ca(NO3)2

moles of AgNO3 = 8.63 x 10-4 moles of AgNO3 = 8.62 x 10-4 mol I

Concentration of I in the original solution = 0.0172 M

But how do I find percentage of calcium iodide in the solution? Can you have grams divided by a volume to find percentage?

Again thanks to anyone that can help.

never mind you use density to find grams.
