SUMMARY
A 10% (by weight) solution of KNO3 has a calculated molality of 1.1 mol/kg and a mole fraction of 0.0194. The calculations were based on 1 g of KNO3 in a total solution weight of 10 g, leading to the determination of moles of KNO3 and water. The molality formula used was moles of KNO3 divided by the mass of water in kilograms, while the mole fraction was derived from the ratio of moles of KNO3 to the total moles in the solution.
