What is the correct molality of a solution prepared by dissolving 0.100 mol of chloroform CHCI3 in 400.0 g of toluene?

The correct molality of the solution can be calculated using the formula: molality = (moles of solute) / (mass of solvent in kg) Given that 0.100 mol of CHCl3 is dissolved in 400.0 g (0.400 kg) of toluene, the molality of the solution is 0.250 m.
