What is the molality of C,H,OH in water solution
which will freeze at - 10°C? [Mol, wt. of C,H,OH
= 46, K, for water = 1.86]
(2) 63.15 m
(4) 5.3 m
(1) 6.315 m
(3) 3.540 m​

Answer 1

Explanation:

5.3 m is the answer

freezing point of pure water =0°C = T°

freezing point of solution =T= -10°C

∆ Tf = T° - (-10) = 10

∆ Tf = Km

m= ∆Tf/ K = 10/1.86
