Which of the following statements explains the correct reasoning for the use of molality (rather than molarity) in this equation? a) As the temperature of a solution changes, its volume will also change, which will affect its molarity but not its molality. b) In solutions, moles are not directly related to grams and the boiling point of a solution is dependent solely on the number of grams of solute. c) 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. d) Molality does not appear in many equations, so it is used here to distinguish this equation from other similar ones.
