`6.02 xx 10^(21)` molecules of urea are present in 100ml of its solution. The concentration of urea solution is

Options

A. 0.001 M
B. 0.1 M
C. 0.02 M
D. 0.01 M

Explanation

To find the concentration of urea in the solution, we will calculate the molarity using the number of molecules given and the volume of the solution. Here’s a step-by-step solution:

### Step 1: Calculate the number of moles of urea
We know that 1 mole of any substance contains \(6.02 \times 10^{23}\) molecules (Avogadro's number).

Given:
- Number of molecules of urea = \(6.02 \times 10^{21}\)
