A saturated calcium iodate solution was prepared by adding solid calcium iodate

A saturated calcium iodate solution was prepared by adding solid calcium iodate to water. The titration of a 38.5 mL sample of a saturated calcium iodate solution required 13.16 mL of a 0.0740 M solution of sodium thiosulfate to reach the endpoint of the titration.

 How many moles of sodium thiosulfate were added? 

How many moles of iodate ions were present in the solution? 

What was the concentration of iodate in the original sample?

 What was the concentration of calcium in the original sample?

 Calculate the value of Ksp for calcium iodate. (The lab procedures and an ICE table will be very helpful.)
