A compound contains 42.9% C, 2.4% H, 16.6% N, and 38.1% O by mass. The addition of 3.16 g of this compound to 75 mL of cyclohexane (d=0.779 g/mL,) gives a solution with a freezing point of 0.0 degrees Celsius. The normal freezing point of cyclohexane is 6.50 degrees Celsius and its freezing point depression constant of 20.2 degrees C/m. What is the molecular formula of the solute ?
