Question

In a laboratory experiment, students synthesized a new compound and found that when 14.57 grams of the compound were dissolved to make 218.6 mL of an ethanol solution, the osmotic pressure generated was 5.65 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?

Molar mass = [ \_\_\_\_ ] g/mol
