A certain substance X condenses at a temperature of 108.9°C. But if a 950.g sample of X is prepared with 105.5g of urea ((NH2)2CO) dissolved in it, the sample is found to have a condensation point of 112.2°C instead. Calculate the molal boiling point elevation constant Kb of X. Round your answer to 2 significant digits
