In a laboratory experiment, students synthesized a new compound and found that when 11.94 grams of the compound were dissolved to make 152.4ml of a benzene solution, the osmotic pressure generated was 6.65atm at 298K. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound.
