Question

Discounting economic considerations, which of the following would be the best to shrinkle an icy road, in quantities proportion to their respective formula weights- (A) NaCl (B) CaCl 2 (C) CuSO 4 .5 H 2 O (D) Al 2( SO 4)3

Molar mass of solute should not be significant here because ‘discounting economic considerations’ is mentioned which means molar mass can be compensated by ‘given mass of solute’. Greater the value of (i), greater will be the depression in f.pt.
