Calculate the molecular weight of a small protein if a 7.0-g sample of the protein dissolved in enough water to make 7.00 x 10 2 mL of solution has an osmotic pressure of 3.8 mmHg at 25.0°C.
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
A 214 mL solution containing 23 g of a protein in toluene had an osmotic pressure of 0.053 atm at 27 oC. What is the molar mass (in g/mol) of the protein? Only enter a numerical value rounded to the nearest whole number in the answer box below. Do NOT type in the unit (g/mol). 2) An NaCl solution is prepared by dissolving 20.0 g NaCl in 150.0 g of water at 25°C. What is the vapor pressure of the...
Osmotic Pressure question: Looking for the molar weight of protein with the following numbers: Started with a sample of 1.928 grams of protein 30 degrees Celcius 66.3 mATM 40 mL of water what is the molar weight of protein in g/mol??? *Gives a hint that the weight should be 10^4 - 10^6 g/mol
A.) A protein solution containing 70.0 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 22.0 mL, what is the molar mass of the protein? B.)What is the boiling point (in °C) of a solution of 8.16 g of I2 in 57.5 g of toluene, assuming the I2 is nonvolatile? (For toluene, Tb = 110.63°C and Kb = 3.40°C·kg/mol.) C.)What is the freezing point...
