A 4.75-g sample of an unknown compound is dissolved in enough water to make 100.0 mL of solution. This solution has an osmotic pressure of 25.0 torr at 25oC. Find the molar mass of the unknown.
In order to determine the molar mass of an unknown protein, 368.7 mg of the protein is dissolved in enough water to give 50.00 mL of solution. The osmotic pressure of this solution is determined to be 2.94 mmHg at 298 K. Estimate the molar mass of this protein. Give an answer to the 100's. Do not include units in your response, only digits.
A solution containing 27.55 mg of an unknown protein per 25.0 mL of solution was found to have an osmotic pressure of 3.22 torr at 25.0oC. What is the molar mass ofthe protein
3a. Calculate the molar mass (in g/mol) of an unknown 1:1 electrolyte if 0.482 g dissolved in 223.1 mL of water at 74.75 °C has an osmotic pressure of 54.4 mmHg. R = 0.082058 L⋅atm⋅mol−1⋅K−1. 1.00 atm = 760 mmHg. Report your answer to THREE significant figures. 3b.
