A solution containing 62 g ethylene glycol in 250 g water is cooled to `-10^(@)C`. If `K_(f)` for water is 1.86 K `mol^(-1)`, the amount of water (in g) separated as ice is :

Options

A. 64
B. 32
C. 16
D. 48

Explanation

To solve the problem of determining the amount of water separated as ice when a solution containing 62 g of ethylene glycol in 250 g of water is cooled to -10°C, we will follow these steps:

### Step 1: Calculate the Depression in Freezing Point
The freezing point of pure water is 0°C. When ethylene glycol is added, the freezing point is lowered. The final freezing point is given as -10°C.

\[ \Delta T_f = T_f(\text{pure solvent}) - T_f(\text{solution}) = 0°C - (-10°C) = 10°C \]
