When is the value of van't Hoff factor more than one?

Explanation

To determine when the value of the van't Hoff factor (i) is more than one, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the van't Hoff Factor (i)**:
The van't Hoff factor (i) is defined as the ratio of the number of particles in solution after dissociation to the number of formula units initially dissolved in the solution. Mathematically, it can be expressed as:
\[
i = \frac{\text{Normal molar mass}}{\text{Observed molar mass}}
