Understanding Molarity

Molarity (M) is a unit of concentration that represents moles of solute per liter of solution.

Formula

* Moles of solute = Molarity (M) x Volume (L)

Calculation

1. Identify the given values:

* Molarity (M) = 2.3 M

* Volume (L) = 0.538 L

2. Plug the values into the formula:

* Moles of KCl = 2.3 M * 0.538 L

3. Calculate the result:

* Moles of KCl = 1.24 moles

Answer: There are 1.24 moles of KCl in 0.538 L of a 2.3 M solution.
