@X@user.full_nаme@X@ @GMU: When 2.824 g оf ureа wаs dissоlved in 109.3 g оf benzene, the freezing point was 276.4 K. What is the formula mass of this compound? The freezing point depression constant for benzene is 5.12 (°C*kg)/mol. The melting point and boiling points are 5.50°C and 80.10°C, respectively.
