This one is stumping me because we haven't covered it yet but somehow, it got into the packet.
You dissolve 2.0 g of solid MX in 250. g of water. You find the freezing point to be 0.028 degrees C. Calculate the Ksp of the solid.
A) 5.6 x 10^-5
B) 7.1 x 10^-7
C) 2.2 x 10^-4
D) 6.3 x 10^-5
E) none of these
My gut inclinations are towards B or E, but I'm really not sure. Any help would be greatly appreciated.
