We’re being asked to calculate for the molality of an aqueous solution prepared by dissolving 0.112 moles of LiCl in 13.7 moles of H2O.

When calculating for molality, we use the following equation: Aqueous solution → water is the solvent

Solute → LiCl

The moles of the solute is already given.

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

Step 1. Calculate the mass of the solvent (in kg).
Step 2. Calculate the molality of the solution.

Step 1. Calculate the mass of the water (in kg).
