  1. delta T = i*Kf*molality
    i = 1 for glucose
    i = 3 for BaCl2
    i = 2 for NaCl
    i = 3 for Na2SO4
    You CAN calculate each with the data given and arrange them from the answers OR you can look at i*m and see which is the largest. The largest value of i*m will have the lowest freezing point (the largest delta T) and the smallest value of i*m will have the highest freezing point (smallest delta T).
