The boiling point of 6.05 g of a pure solvent is measured to be 48.000 ºC. When 20.00 g of an unknown solute (assume the van 't Hoff factor = 1.0000 for the solute and Kb = 4.85 °C/m for the solvent) is added to the solvent the boiling point is measured to be 55.500 ºC . What is the molality ( in m) of the solution?(give your answer to two decimal places)
