Answer:
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
