How much water should be added to 0.07 moles of KCL to prepare a 0.5m solution

Volume = 0.14 L

Explanation:

This is a simple Molarity problem in which we are given with,

Moles = 0.07 moles

Molarity = 0.5 mol. L⁻¹

Volume = ?

Now, as,

Molarity is the amount of solute dissolved per unit volume of solution. It is expressed as,

Molarity = Moles / Volume of Solution

So, Solving for Volume,

Volume = Moles / Molarity

Now, putting value of Moles and Molarity,

Volume = 0.07 mol : 0.5 mol. L⁻¹

Volume = 0.14 L
