STATEMENT -1 : Molality is equal to molarity, if density of solution is one. and STATEMENT -2 : Molality does not depend on the temperature.

Assertion : The molality of the solution does not change with change in tempc- nature. : The molality is expressed in units of moles per 1000 g of solvent. Reason

Assertion (A): A molar solution is more concentrated than molal solution. Reason (R): A molar solution contains one mole of solute in 1000 mL of solution.

Assertion: For calculating the molality or the mole fraction of solute, if the molarity is known, it is necessary to know the density of the solution. Reason: Molality, molarity and the mole fraction of solute can be calculated from the weight percentage and the density of the solution.

Assertion: One molar aqueous solution is more concentrated than that of 1 molal aqueous solution . Reason : Molarity is a function of temperature as volume depends on temperature.
