Question

Quizplus · Accepted Answer

Molality is defined as the number of moles of solute per kilogram of solvent. In this case, we have 0.112 moles of LiCl and 13.7 moles of H2O. The molar mass of H2O is 18.015 g/mol, so the mass of H2O in the solution is 13.7 moles * 18.015 g/mol = 246.5 g. Therefore, the molality of the solution is 0.112 moles / 0.2465 kg = 0.454 m.
