We’re being asked to calculate for the molality of 18 *% by weight **aqueous solution of CdSO _{4}*

When calculating for molality, we use the following equation:

$\overline{){\mathbf{molality}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{mol}\mathbf{}\mathbf{solute}}{\mathbf{kg}\mathbf{}\mathbf{solvent}}}$

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

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

**Step 1**. Determine the **composition** of the solution.

What is the molality of a solution of 18% by mass cadmium sulfate, CdSO_{4} (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
