Question

Why is 1 molar solution more concentrated than 1 molal solution?

Answer 1

1 molar aqueous solution is more concentrated than 1 molal aqueoussolution because 1 molar solutioncontain 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. ... Hence concentration will be more in 1 molar aqueous solution.

Answer 2

the water has the density of 1 kg/lit If we need less than 1. kg of pure water
one mole of solute is dissolved by the less than kg of solute this molarity of solution is greater than molality of the solution
