A certain substance X melts at a temperature of -4.3 °C. But if a 900. g sample of X is prepared with 46.80 g of urea ((NH,) CÓ) dissolved in it, the sample is found to have a melting point of -10.8 °C instead. Calculate the molal freezing point depression constant K, of X. Round your answer to 2 significant digits.
