We’re being asked to calculate for the molality of the solution prepared by dissolving 39.0 g of KCl in 225 mL of water.
When calculating for molality, we use the following equation:
We will calculate the molality of the solution using the following steps:
Step 1: Calculate the moles of solute.
Step 2: Calculate the mass of the solvent (in kg).
Step 3: Calculate the molality of the solution.
KCl → dissolved in water → Solute
Water (H2O) → where KCl is dissolved → Solvent
Step 1: Calculate the moles of KCl.
A solution was prepared by dissolving 39.0 g of KCl in 225 mL of water. Calculate the molality of KCl in the solution.
