The molality of a solution prepared by dissolving 13.3 g of kcl in 750.0 ml of water is 0.23 moles per kilogram.
What is molality?
The molality of a solution is the number of moles of solute present in per kilogram of the solvent is called the molality of the solution and cannot be affected by temperature.
Molality = weight / mass × 1000/ volume if water in ml.
mass of KCl = 74.55
substituting the value in the formula,
molality = 13.3 g / 74.55 × 1000/ 750
molality = 0.23 moles per kilogram.
Therefore, 0.23 moles per kilogram is the molality of a solution prepared by dissolving 13.3 g of KCL in 750.0 ml of water.
