A student creates an aqueous solution that is 0.200 m K2S. Assuming complete dissociation of the solute and use the expected van't Hoff factor for the solute. Kb for water is 0.512 celsius/m and Kf is 1.86 celsius/m. The boiling point of pure water is exactly 100 degrees celsius and the freezing point is exactly 0 degrees celsius. What concentration of K2S, in morality (m), would produce a solution whose freezing point was -2.0 degrees celsius?
