An organic compound was prepared and purified by chromatography. A conductivity measurement showed the compound to be a nonelectrolyte. Elemental analysis gave an empirical formula of CH3O. A 0.127 g sample of the compound was dissolved in water and diluted to 100.0 mL, and the osmotic pressure of that solution was determined to 0.492 atm at 20°C. Determine the molar mass of the compound. (R = 0.0821 L·atm/K·mol) None of the above 42.1 g/mol 62.1 g/mol 32.1 g/mol 52.1 g/mol
