If we have `10` molal urea solution, Calculate mole fraction of urea in this solution `&` also calculated `% W//W` of urea `(MW=60)`.

Explanation

To solve the problem, we will calculate the mole fraction of urea in a 10 molal urea solution and then calculate the percentage weight by weight (% W/W) of urea.

### Step 1: Understand the definition of molality
A 10 molal (10 m) urea solution means that there are 10 moles of urea dissolved in 1 kilogram (1000 grams) of solvent (water).

### Step 2: Calculate the number of moles of urea
Given:
- Moles of urea (solute) = 10 mol
