Hemoglobin is a large molecule that carries oxygen in human blood. A water solution that contains 0.263

Question:

Hemoglobin is a large molecule that carries oxygen in human blood. A water solution that contains 0.263 g of hemoglobin (abbreviated here as Hb) in 10.0 mL of solution has an osmotic pressure of 7.51 torr at 25 °C . What is the molar mass of hemoglobin?

Strategy

Use the measurement of the osmotic pressure to find the number of moles of solute; combine that number with the mass data given in the problem to find the molar mass.
