In a laboratory experiment, students synthesized a new compound and found that when 11.35 grams of the compound were dissolved to make 191.3 mL of a water solution, the osmotic pressure generated was 8.06 atm at 298 K. The compound was also found to be nonvolatile and a non-electrolyte.
What is the molecular weight they determined for this compound?
