Final answer:
The molality of the solution prepared by dissolving 0.114 mole of chloroform in 476 g of toluene is 0.239 m.
Step-by-step explanation:
The molality of a solution is calculated by the number of moles of solute per kilogram of solvent. To find the molality of a chloroform solution in toluene, we use the given amounts: 0.114 moles of chloroform dissolved in 476 grams (or 0.476 kg) of toluene.
Molality (m) = moles of solute / kilograms of solvent
= 0.114 moles / 0.476 kg
= 0.239 mol/kg (or 0.239 m)
This means the molality of the chloroform solution in toluene is 0.239 m.
