The mole fraction of urea in an aqueous urea solution containing 900 g of water is 0.05. If the density of the solution is `1.2 g cm^(-3)`, the molarity of urea solution is __________
Given data: Molar masses of urea and water are `60 g "mol"^(-1)` and `18 g "mol"^(-1)` , respectively)

Explanation

To find the molarity of urea in the given aqueous solution, we will follow these steps:

### Step 1: Calculate the number of moles of water
Given:
- Mass of water = 900 g
- Molar mass of water = 18 g/mol

Using the formula for moles:
