1 molar solution is a solution in which 1 mole of a compound is dissolved in a total volume of 1 litre.

Molality, also called molalconcentration, is a measure of the concentration of a solute in a solutionin terms of amount of substance in a specified amount of mass of the solvent.

1 molar aqueous solution is more concentrated than 1 molal aqueous solution .

1 molar solution contain 1 mole of solute in 1 litre of the solution which include both solute and solvent.

So, the mass of solvent (i.e. water) is less than 1000 gram. Therefore 1 molar aqueous solution contains 1 mole of solute in less than 1000 gram of solvent .

Whereas 1 molal solution has 1 mole of solute in 1000 gram of solvent.

Hence concentration will be more in 1 molar aqueous solution.
