Question

Among 1 M and 1 m solutions of glucose, which one is more concentrated and why?

Answer 1

Among 1 M and 1 m solutions of glucose, the 1 M solution is more concentrated because it contains 1 mole of glucose dissolved in 1 litre of solution, whereas the 1 m solution contains 1 mole of glucose dissolved in 1 kilogram of solvent, which results in a larger total volume. Since the same amount of solute is present but the total volume is smaller in the 1 M solution, it is more concentrated than the 1 m solution.
