A solution containing 15 g urea (molar mass `=60" g mol"^(-1)`) per litre of solution in water has the same osmotic pressure (isotonic) as a solution of glucose (molar mass = `180" g mol"^(-1)`) in water. Calculate the mass of glucose present in one litre of its solution.

Explanation

To solve this problem, we need to determine the mass of glucose in one liter of its solution that has the same osmotic pressure as a solution containing 15 g of urea per liter.

### Step-by-Step Solution:

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