What is the molarity of a 5.00 x 102 ml solution containing 2490 g of KI?

Answer 1

how many moles of KI?

M = moles/liter

Answer 2

I'm dumb. I'm sorry I still don't understand.

Answer 3

5.00*10^2ml = 500ml = .5L

KI has molar mass 166, so you have 15 moles of KI

15moles/.5L = 30moles/L = 30M

cinchy, right?

Answer 4

How'd you get 15 moles?
