Understanding Molarity

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

Formula:

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

Applying the Formula

1. Identify the solute and solvent:

- Solute: Potassium Chloride (KCl)

- Solvent: Water (assuming the solution is aqueous)

2. Plug in the values:

- Moles of solute (KCl) = 4.00 moles

- Liters of solution = 3.00 L

3. Calculate the molarity:

M = 4.00 moles / 3.00 L = 1.33 M

Answer: The molarity of the solution is 1.33 M.
