A certain substance X melts at a temperature of 7.6 °C. But

A certain substance X melts at a temperature of 7.6 °C. But if a 750. g sample of X is prepared with 30.54 g of urea ((NH₂)₂CO) dissolved in it, the sample is found to have a melting point of 2.8 °C instead. Calculate the molal freezing point depression constant KF of X. Round your answer to 2 significant digits.
