A 150.0 ml of sample of an aqueous solution at 25 degrees celcius contains 15.2 mg of unknown electrolyte compound. If the solution has an osmotic pressure of 8.44 torr, what is the molar mass of the unkown compound?\
A protein solution containing 90.0 mg of the protein (dissolved in water) displays an osmotic pressure of 319.88 Pa at 310.15 K. If the volume of the protein solution is 13.0 mL, what is the molar mass of the protein? g/mol
The osmotic pressure of a solution containing 22.7 mg of an unknown protein in 50.0 mL of solution is 2.88 mm Hg at 25.0°C. Determine the molar mass of the protein. Select one: O a. 3.85 x 10 g/mol O b.3.85 g/mol O c. 2.46 x 10 g/mol O d. 1.47 x 10 g/mol e. 2.93 x 109 g/mol
The osmotic pressure of an aqueous solution of a certain protein was measured in order to determine the protein’s molar mass. The solution contained 3.50-g of protein dissolved in sufficient water to form 5.00-L of solution. The osmotic pressure of the solution at 25oC was found to be 1.54-mmHg. (Hint: Remember to convert mmHg to atm) Calculate the molar mass of the protein.
1. When 0.713 grams of a protein were dissolved in 72.5 mL of solution at 28.5 degrees C, the osmotic pressure was found to be 35.6 torr. Calculate the molar mass of the protein. 2. Calculate the molality of an aqueous solution that is 8.1% by mass calcium chloride. You might need to know that the density is 1.20 g/mL.
