Understanding Molarity

Molarity (M) is a measure of concentration that expresses the number of moles of solute per liter of solution.

Formula

Molarity (M) = moles of solute / liters of solution

Calculation

1. Identify the given values:

* Moles of solute (KCl) = 202 mol

* Liters of solution = 7.98 L

2. Plug the values into the formula:

M = 202 mol / 7.98 L

3. Calculate the molarity:

M ≈ 25.3 M

Answer

The molarity of the solution is approximately 25.3 M.
