If a student knows the mass of a solute and the volume of the solvent, what else must be known to compute the molality of the solution?
A)The density of the solvent
B)The temperature of the solvent
C)The volume of the solute
D)The size of the container

Question

Quizplus · Accepted Answer

Molality is calculated as the number of moles of solute per kilogram of solvent. Knowing the mass of the solute allows for the calculation of moles of solute, but the mass of the solvent is needed to find molality. The density of the solvent is required to convert the known volume of the solvent to its mass.
