Calculate the freezing point of a one-molar aqueous solution (density 1.06 g `mL_(-1) `) of KBr. `K_"f"` for water = 1.86 K kg `mol^(-1)`. Atomic mass: K = 39, Br = 80.

Explanation

To calculate the freezing point of a one-molar aqueous solution of KBr, we will follow these steps:

### Step 1: Understand the Problem
We need to find the freezing point of a 1 molar aqueous solution of KBr. The freezing point of pure water is 273.15 K, and we will use the formula for freezing point depression to find the new freezing point.

### Step 2: Identify the Required Values
- **Freezing point depression constant (Kf) for water**: 1.86 K kg/mol
- **Density of the solution**: 1.06 g/mL
