A solution of cane sugar at `27^@C` develops an osmotic pressure of 4.93 atm. Calculate the f.p. of this solution (molecular depression constant for 100 g of water is 18.6).

Explanation

To solve the problem, we need to calculate the freezing point depression of a cane sugar solution based on the given osmotic pressure. Here’s a step-by-step solution:

### Step 1: Identify the given values
- Osmotic pressure (π) = 4.93 atm
- Freezing point depression constant (Kf) = 18.6 °C kg/mol for 100 g of water

### Step 2: Convert Kf to kg/mol
Since Kf is given for 100 g of water, we need to convert it to the per kg value:
