How many moles and how many grams of HCI are present in 250 ml of 0.5 M HCl solution?

Explanation

To solve the problem of how many moles and how many grams of HCl are present in 250 ml of a 0.5 M HCl solution, we can follow these steps:

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