A certain substance X condenses at a temperature of 128.4 °C. But if a 800. g sample of X is prepared with 81.06 g of urea ((NH),CO) dissolved in it, the sample is found to have a condensation point of 129.7 °C instead. Calculate the molal boiling point elevation constant K, of X. Round your answer to 2 significant digits. -1 °C-mol kg
