Question

Out of 0.1molal and 0.1molar solution which one is more concentrated and why?

Answer 1

Sorry I only know that 0.1 molar is more concentrated but I even don’t know why

Answer 2

Uppercase m denotes molarity and Lowercase m denotes molality

Both molality and molarity almost same in nature

In 1 molar solution, 1 mole of solute is in 1 litre of solution That means solute and solvent makes  1 litre.

M and m are not replaceable at elevated solute concentrations, in situations where the temperature changes, or when the solvent is not water.

So 0.1 molar solution is more concentrated than 0.1 molal solution.
