A)3.37
B)0.278
C)2.78
D)0.212
E)The density of the solution is needed to solve the problem.

Question

Quizplus · Accepted Answer

Molality is defined as the number of moles of solute per kilogram of solvent. To calculate the molality of the solution, we need to know the mass of the solution, the mass of the solute, and the molar mass of the solute.The mass of the solution can be calculated using the density of the solution. However, the density of the solution is not given in the question, so we cannot calculate the molality of the solution.
