A 0.25 liter of potassium chloride solution contains 0.75 moles of KCl. What is the concentration of this solution?

The concentration of the KCl solution is 3.0 M

Explanation:

Step 1: Data given

Volume of KCl = 0.25 L

Number of moles KCl = 0.75 moles

Molar mass KCl = 74.55 g/mol

Step 2: Calculate concentration of KCl

Concentration KCl solution = moles KCl / volume solution

Concentration KCl solution = 0.75 moles / 0.25 L

Concentration KCl solution = 3.0 M

The concentration of the KCl solution is 3.0 M
