What is the molarity when 1 mol solute is dissolved to make 1 L of solution?

Answer and explanation
Correct answer: 1 M
Molarity is the amount of solute in moles divided by the volume of the final solution in litres. Using M = n/V, here n = 1 mol and V = 1 L, so M = 1/1 = 1 mol L⁻¹, or 1 M. Therefore option A is correct. The solvent volume before dissolution must not replace the final solution volume.
