e equation used to calculate the change in freezing point (AT) of a substance is AT₁= = Km ere K, is the freezing point depression constant and m is the molality of the solution. Which of the statements explains why molality is used instead of molarity in this equation? O Molality does not appear in many equations, so it is used here to distinguish this equation from other similar ones. O The equation was originally published with m as a typo, rather than M, but the values are close enough that the equation is still valid. O As the temperature of a solution changes, its volume will also change, which will affect its molarity but not its molality. O In solutions, moles are not directly related to grams and the freezing point of a solution is dependent solely on the number of grams of solute.
