What does molarity tell us that percent solution information does not tell us?

Molarity tell us about the concentration of moles of solute in a solution.

Explanation:

Chemical substances are measured in terms of mole. Mole is defined as the amount of substance which contains 6.022*10²³ particles, ions or atoms. In System of international, amount of substance is measured in moles. So molarity tells us more information about amount of solute in a solution as compared to percent solution.
