`45 g` of ethylene glycol `C_(2)H_(6)O_(2)` is mixed with `600 g` of water. Calculate (a) the freezing point depression and (b) the freezing point of solution.
Given`K_(f)=1.86 K kg mol^(-1)`.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the number of moles of ethylene glycol (C₂H₆O₂)

First, we need to find the molecular weight of ethylene glycol:
- The molecular formula of ethylene glycol is C₂H₆O₂.
- The molecular weight can be calculated as follows:
- Carbon (C): 12.01 g/mol × 2 = 24.02 g/mol
