I need help with this Chemistry problem please.

When 274. mg of a certain molecular compound X are dissolved in 75. g of cyclohexane (C6H12), the freezing point of the solution is measured to be 5.7 C. Calculate the molar mass of x. If you need any additional information on cyclohexane, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to the correct number of significant digits. chemical formula name melting point (Tm) boiling point (T) heat capacity at 25C (c) Jign-c-1 heat of fusion (AHtus) kJ mol-1 heat of vaporization (Hvap) molal freezing point depression constant (1) *C kg-mol-1 kJ.mol-1 water H20 0.00C 100.0'C 4.184 6.01 40.65 1.86 methanol CH3OH -97.53C 64.6C 2.53 3.215 35.21 ethanol CH3CH2OH -114.4C 78.29"C 2.238 4.931 38.56 1.99 acetic acid HCH3CO2 16.64C 117.9C 2.06 11.73 23.70 3.63 hexane C6H14 -95.35C 68.73" 2.27 13.08 28.85 1 octane CgH18 -56.82"C 125.67C 2.23 20.73 34.41 benzene 66 5.538"C 80.09C 1.63 9.87 30.72 5.07 cyclohexane C6H12 6.7C 80.7C 1.841 2.68 29.97 20.8 benzonitrile C6H5CN -12.82C 191.00 1.602 9.1 45.9 5.35 dibenzyl ether (C6H5CH2)20 1.8C 298.C 45.6 6.17 formamide NH2COH 2.57C 217." 8.44 60.15 1 4.25
