MISSED THIS? Watch KCV: Solution Concentration: Molarity, Molality, Parts by Mass and Volume, Mole Fraction , IWE: Calculating Concentrations; Read Section 14.5. You can click on the Review link to access the section in your eText. An aqueous KNO3 solution is made using 56.2g of KNO3 diluted to a total solution volume of 2.00 L. (Assume a density of 1.05g/mL for the solution.) Calculate the molality of the solution. Express the molality to three significant figures. X Incorrect; Try Again; 2 attempts remaining You have reported the molarity (moles per liter) of the solution, but you should report the molality, which has units of mol/kg (kilogram of solvent). Part C Calculate the mass percent of the solution. Express the mass percent to three significant figures
