How much amount of NaCl should be added to 600 g fo water `(varphi =1.00 g//mL)` to decrease freezing point of water to `-0.2^(@)C`? ___________________. (The freezing point depression constant for water `=2K kg "mol"^(-1)`)

Explanation

To solve the problem of how much NaCl should be added to 600 g of water to decrease the freezing point to -0.2°C, we will follow these steps:

### Step 1: Identify the given data
- Mass of water (solvent) = 600 g
- Density of water = 1.00 g/mL (this is not directly needed for calculations)
- Freezing point of solution = -0.2°C
- Freezing point depression constant (Kf) for water = 2 K kg/mol
