      Which aqueous solution has higher concentration ; 1 molar or 1 molal having the same solute?

    Answer:

                      In aqueous solution, the density of water is normally taken as one. This means that 1m solution has 1 mole of the solute dissolved in 1000 g or 1000 mL of water. At the same time, 1M solution contains 1 mole of the solute in 1000mL solution which is the volume of both the solute and the solvent present in the solution. This clearly shows that the solvent present in 1M solution is less as compared to 1 m solution. Therefore, 1M solution is more concentrated than 1 m solution.
