A `5%` solution of cane sugar is isotonic with `0.877%` solution of urea. Calculate the molecular mass of urea if the molecular mass of cane sugar is `342`.

Explanation

To solve the problem of finding the molecular mass of urea given that a 5% solution of cane sugar is isotonic with a 0.877% solution of urea, we can follow these steps:

### Step 1: Understand the concept of isotonic solutions
Isotonic solutions have the same osmotic pressure. Therefore, the osmotic pressure of the cane sugar solution will be equal to that of the urea solution.

### Step 2: Write down the given data
- Concentration of cane sugar solution = 5% (which means 5 g of sugar in 100 mL of solution)
- Concentration of urea solution = 0.877% (which means 0.877 g of urea in 100 mL of solution)
