Equal weights of two substances X and Y are dissolved in equal volumes of water. The osmotic pressure of the solution containing Y is five times the osmotic pressure of the solution containing X. What is the molecular weight of X if that of Y is 60?

Explanation

To solve the problem, we will use the concept of osmotic pressure and the relationship between the concentrations of the solutions of substances X and Y.

### Step-by-Step Solution:

1. **Understanding Osmotic Pressure**:
The osmotic pressure (\( \pi \)) of a solution is given by the formula:
\[
\pi = CRT
