Determine the molar mass of a solute from osmotic pressure. In a laboratory experiment, a student found that a 176-mL aqueous solution containing 2.408 g of a compound had an osmotic pressure of 21.3 mm Hg at 298 K. The compound was also found to be nonvolatile and a nonelectrolyte. What is the molar mass of this compound? g/mol
