In a laboratory experiment, students synthesized a new compound and found that when 12.21 grams of the compound were dissolved to make 173.0 mL of a ethanol solution, the osmotic pressure generated was 9.42 atm at 298 K. The compound was also found to be nonvolatile and a non-electrolyte. What is the molar mass they determined for this compound?
