Whats the difference between molarity and molality?

WebThe molarity of H 2SO 4 is 18 M. Hence, 1 L of H 2SO 4 corresponds to 18 moles of H 2SO 4. The density of H 2SO 4 is 1.8 g/mL. Thus 1 L of H 2SO 4 corresponds to 1800 g or 1.8 kg. Out of this 18×98=1.764kg corresponds to H 2SO 4. Hence, the mass of water is 1.8kg−1.764kg=0.036kg. Hence, the molality of the solution is 0.03618 =500m.
