To find the molarity (M) of a solution, you can use the formula:

$M = \frac{\text{moles of solute}}{\text{volume of solution in liters}}$

Given:

• Moles of KCl = 0.505 mol
• Volume of solution = 7.98 L

Now, applying the values to the formula:

$M = \frac{0.505 \, \text{mol}}{7.98 \, \text{L}} = 0.0633 \, \text{M}$

So, the molarity of the solution is 0.0633 M.

Here are five related questions for further exploration:

1. How does temperature affect the molarity of a solution?
2. How do you prepare a solution with a specific molarity?
3. What is the relationship between molarity and concentration?
4. How does the concept of molality differ from molarity?
5. How would you calculate the molarity of a diluted solution?

Tip: Always ensure that the volume used in molarity calculations is in liters (L), not milliliters (mL).
