We’re being asked to calculate for the molality of total ions in an aqueous solution prepared by dissolving 0.400 moles of magnesium chloride in 850.0 g of water.

When calculating for molality, we use the following equation: The moles of MgCl2 is given but we were asked to determine the molality of total ions

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

Step 1. Determine the ions present in the solution.
Step 2. Calculate the moles of the ions present in the solution.
Step 3. Calculate the mass of the solvent (in kg).
Step 4. Calculate the molality of total ions.

Step 1. Determine the ions present in the solution.
