Calculate the Van't Hoff factor when `0.1 mol NH_(4)Cl` is dissolved in `1 L` of water. The degree of dissociation of `NH_(4)Cl` is `0.8` and its degree of hydrolysis is `0.1`.

Explanation

To calculate the Van't Hoff factor (i) for the dissociation of ammonium chloride (NH₄Cl) in water, we need to consider both the degree of dissociation and the degree of hydrolysis. Here’s a step-by-step solution:

### Step 1: Understand the Dissociation of NH₄Cl
NH₄Cl dissociates in water as follows:
\[ \text{NH}_4\text{Cl} \rightarrow \text{NH}_4^+ + \text{Cl}^- \]

### Step 2: Calculate the Initial Concentration of NH₄Cl
Given:
