A solution containing 2.7 gm of urea per 100 ml of the solution is isotonic with a solution of sucrose. How many grams of sucrose are present in 500 mL of the solution ?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the concept of isotonic solutions
Isotonic solutions have the same osmotic pressure. Therefore, the osmotic pressure of the urea solution will equal the osmotic pressure of the sucrose solution.

### Step 2: Write the formula for osmotic pressure
The osmotic pressure (π) can be expressed using the formula:
\[
