What total volume is needed to prepare a 1.5 molar solution using 0.75 mole solute?

Answer and explanation
Correct answer: 0.5 litre
Molarity is defined as moles of solute divided by the total volume of solution in litres. Rearrange M = n/V to obtain V = n/M. Substitution gives V = 0.75 mol ÷ 1.5 mol L−1 = 0.50 L. Hence, option A is correct. This is the final solution volume, not necessarily the initial volume of solvent used.
