How much ml of 0.200 m of KSCN will be needed after addition of 30.0 ml 0.1100 of AgNO3 to 0.3658 g KI dissolved in 100 ml water?(Ksp= 8.3*10^(-17)for AgI

You don't have a clear question. How many mL is a question, of course, but to do what? And is that m or M. I assume you know there is a difference.
