**DrBob222**, Thursday, February 9, 2012 at 10:22pmdelta T = i*Kf*m

You want to know which solution produces the higher delta T. m is the same, Kf is the same, the only difference is i. i is the van't Hoff factor which is the number of particles.

A does not ionize (at least I assume it doesn't). B ionizes into two particles, C into 3 particles and D into four particles. So stick 1, 2, 3, 4 into the equation. Which gives the higher number for delta T?
