Solution

## The correct option is A 1000g of solventThe explanation for the correct option.(A) - 1000g of solventMolality (m): The number of moles of solute dissolved in 1000g (1 kg) of a solvent is known as the molality of the solution.$\mathrm{Molality}=\frac{\mathrm{Number}\mathrm{of}\mathrm{mole}\mathrm{of}\mathrm{solute}}{\mathrm{Mass}\mathrm{of}\mathrm{solvent}\mathrm{in}\mathrm{gram}}×1000$The explanation for incorrect options.(B)- 1L of solventWhen 1 mole of a substance is present in 1 L of a solution is known as a normal solution.(C) 1L of solution A molar solution is defined as an aqueous solution that contains 1 mole (gram-molecular weight) of a compound dissolved in 1 litre of a solution.(D)- 22.4L of solutionOne of the most practical results of the Avogadro's is the molar volume of gases Vm which is 22.4 dm3/mol.Hence, Option (A) is the correct option.
