@X@user.full_name@X@ @GMU: When 10.93 g of citric acid was dissolved in 105.9 g of benzene, the freezing point was 275.9 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.
