420. mg of an unknown protein are dissolved in enough solvent to make 5.00 mL of solution. The osmotic pressure of this solution is measured to be 0.323 atm at 25.0 °C. Calculate the molar mass of the protein. Round your answer to 3 significant digits. g mol ?

The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant R. Suppose the osmotic pressure of a certain solution is measured to be 20. atm at an absolute temperature of 351. K. Write an equation that will let you calculate the molarity c of this solution. Your equation should contain only symbols. Be sure you define each symbol other than R. Your equation: C = Definitions of your symbols: = 20, atm = 351.
