Question

Which one is more concentrated - Aqueous solution of 3m or 3M?

Answer 1

Answer:

3 molar solution is more concentrated than 3 molal solution

Answer 2

Answer:

, the mass of solvent (i.e. water) is less than 1000gram in molar solution. Therefore one molar aqueous solution contains one mole of solute in less than 1000gram of solvent whereas one molal solution has one mole of solute in 1000 gram of solvent.

Hence concentration will be more in one molar aqueous solution
