The number of moles of the solute present in 500 ml of 0.05 M solution is:

Explanation

To find the number of moles of solute present in a 500 ml of 0.05 M solution, we can follow these steps:

### Step 1: Understand the formula for molarity
Molarity (M) is defined as the number of moles of solute divided by the volume of solution in liters. The formula is:
\[ \text{Molarity (M)} = \frac{\text{Number of moles of solute}}{\text{Volume of solution in liters}} \]

### Step 2: Convert volume from ml to liters
The volume of the solution is given as 500 ml. To convert this to liters, we use the conversion factor:
