Calculate the amount of ice that will separate out on cooling containing `50 g `of ethylene glycol in `200 g` of water to `-9.3^(@)C (K_(f)` for water =`1.86 K mol^(-1) kg`)

Options

A. `38.71g`
B. `38.71mg`
C. `42g`
D. `42mg`

Explanation

To solve the problem of calculating the amount of ice that will separate out when cooling a solution containing 50 g of ethylene glycol in 200 g of water to -9.3°C, we will follow these steps:

### Step 1: Identify the given values
- Mass of ethylene glycol (W_A) = 50 g
- Mass of water (W_B) = 200 g
- Freezing point depression constant for water (K_f) = 1.86 K kg/mol
- Final temperature (T_f) = -9.3°C
- Initial freezing point of water (T_i) = 0°C
