We’re being asked to calculate for the molality of an aqueous solution prepared by dissolving 126 g NaCl in a total volume of 1.15 L.
When calculating for molality, we use the following equation:
Aqueous solution → water is the solvent
Solute → NaCl
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.
An aqueous NaCl solution is made using 126 g of NaCl diluted to a total solution volume of 1.15 L .
Calculate the molality of the solution. (Assume a density of 1.08 g/mL for the solution.)
