What is the molality of a solution of 18% by mass cadmium sulfate, CdSO4 (molar mass = 208.46 g/mol) by mass?

A) 0.53 m

B) 0.44 m

C) 0.86 m

D) 2.10 m

E) 1.05 m


We’re being asked to calculate for the molality of 18 % by weight aqueous solution of CdSO4

When calculating for molality, we use the following equation:

molality = mol solutekg solvent

We will calculate the molality of the solution using the following steps:

Step 1Determine the composition of the solution.
Step 2Calculate the molality of the solution.

Step 1. Determine the composition of the solution.
