Question

for a given solution of density 1g/ml , why molality is greater than morality

Answer 1

If density of solution is 1g/ml,
Mass of solution=volume of solution
But mass of solution>mass of solvent (solution=solute+solvent)
So the denominator in M is greater than denominator in m, whereas numerator remains same... so molality >molarity when density=1g/ml
