One of the easiest ways of determining the molar mass of a protein is to determine the osmotic pressure of a solution containing the protein. The osmotic pressure of a solution containing 30.06 mg of an unknown protein dissolved in 14.0 mL of solution is 1.34 torr at 23.06°C. Find the molar mass of the unknown protein in kg/mol. Report your answer to 3 sig figs, but do NOT include units.
467. 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 0.0930 atm at 25.0 °C. Calculate the molar mass of the protein. Be sure your answer has the correct number of significant digits.
163.mg of an unknown protein are dissolved in enough solvent to make 5.00mL of solution. The osmotic pressure of this solution is measured to be0.0516atm at 25.0°C. Calculate the molar mass of the protein. Round your answer to 3 significant digits.
Problem Page 457.mg of an unknown protein are dissolved in enough solvent to make 5.00mL of solution. The osmotic pressure of this solution is measured to be 0.301atm at 25.0°C. Calculate the molar mass of the protein. Round your answer to 3 significant digits.
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. Calculate the required mass of an unknown nonelectrolyte (ℳ = 131.5599 g/mol) dissolved in 140.1 g of solvent that gives a solution that boils at 36.04 °C. The boiling point of the...
The osmotic pressure of a solution containing 23.9 mg of an unknown protein in 50.0 mL of solution is 2.88 mmHg at 25∘C. Part A Determine the molar mass of the protein. Determine the molar mass of the protein. 259 g/mol 4.06 g/mol 154 g/mol 3.08×103 g/mol
A protein solution containing 80.0 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 16.0 mL, what is the molar mass of the protein
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 18.0 mL, what is the molar mass of the protein?
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 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.
