  1. The highest freezing point will be the one with the smallest delta T and that will occur for the material with the smallest number of particles; i.e., highest van't Hoff factor x molality or i*m
    A. 0.1M KCl im = 2*0.1
    B. 0.05M NaCl im = 2*0.05
    C. 1M AlPO4 im = 1*3
    D. 0.1MMgSO4 im = 2*0.1

  3. Sir, It's MOLARITY (M) not molality (m) given in the question. Do we still have to follow the same formula of i*m...??
