A `1.17%` solution of `NaCl` is isotonic with `7.2%` solution of glucose. Calculate the Van't Hoff factor of `NaCl`.

Explanation

To find the Van't Hoff factor (i) for NaCl, we can follow these steps:

### Step 1: Understand the Problem
We know that a 1.17% solution of NaCl is isotonic with a 7.2% solution of glucose. This means that the osmotic pressure of both solutions is the same.

### Step 2: Define the Concentrations
- For the NaCl solution:
- Mass of NaCl = 1.17 g
