Why is camphor preferred as a solvent for measuring the molecular mass of naphthalene by Rast method?

Explanation

To answer the question of why camphor is preferred as a solvent for measuring the molecular mass of naphthalene by the Rast method, we can break down the reasoning into several key points:

### Step-by-Step Solution:

1. **Understanding the Rast Method**:
The Rast method is a technique used to determine the molecular mass of a solute by measuring the depression of the melting point of a solvent when the solute is added.

**Hint**: Familiarize yourself with colligative properties, specifically how the addition of a solute affects the melting point of a solvent.
