A certain substance X condenses at a temperature of 114.3 °C. But if a 250. g sample of X is prepared with 12.12 g of urea ((NH,),CO) dissolved in it, the sample is found to have a condensation point of 116.0 °C instead. Calculate the molal boiling point elevation constant K₁, of X. Round your answer to 2 significant digits.
