Solution:
Molality:-It is a measure of the concentration of a solute in a solution in terms of amount of substance in a specified amount of mass of the solvent
Therefore,
Molality = moles solute / kg solvent
Therefore kg solvent = moles solute / molality
moles solute = mass / molar mass
= 25.31 g / 101.1 g/mole
= 0.2503 mole
kg solvent = 0.2503 mole / 0.1982 m
= 1.263 kg
= 1263 g
This is the required answer.
