A 0.608 g sample of a protein was dissolved in 25.00 mL of water and the resulting osmotic pressure at 305 K was measured at 1.84 x 10-2 atm.  What is the molar mass of this protein?

What is the molar mass of a protein if 5.87 mg per 10 mL gives an osmotic pressure of 2.45 torr at 25 °C?

The molar mass of an enzyme was measured by dissolving the 3.221 grams of the enzyme in 1.00 liter of water. The osmotic pressure of the solution was 5.746 cm of solution at 20°C (assume the density of the solution is 1.00 g/mL and the density of mercury is 13.56 g/mL). What is the molar mass of the enzyme?

Suppose you have 1.7 g NaCl in 100.0 g of water. Calculate the molality based on the molar mass. Then calculate the ionic molality.

5. Lysozyme is an enzyme that cleaves cell walls. A 0.100-L sample of a solution of lysozyme that contains 0.0750 g of the enzyme exhibits an osmotic pressure of 1.32 x 103 atm at 25 °C. What is the molar mass of lysozyme?

At 25.0 °C, 100.0 mL of an aqueous solution containing 45.2 mg of a molecular solute has an osmotic pressure of 18.4 Torr. The molar mass of the solute is ___ g/mol.

0.6244 g of an unknown non-electrolyte is dissolved in enough water to make 200.0 mL of solution at 34.8 °C, giving an osmotic pressure of 0.04359 atm. What is the molar mass, in grams per mole, of the substance?

You have a solution of 10.0 g of sucrose in 100.0 of water. Calculate the molality based on the molar mass of the compound. Then calculate the ionic molality.

An aqueous solution containing 9.15 g of a certain non-electrolyte has a volume of 590 mL. The solution's osmotic pressure at 25 °C was found to be 1.75 torr. Calculate the molar mass of the compound. 2.17×10-1 g/mol 2.17×102 g/mol 1.38×104 g/mol 1.65×105 g/mol 1.67×107 g/mol
