Immunoglobulin G(IgG), formerly called gamma globulin, is a principle antibody in blood serum. A 0.955 gram sample of immunoglobulin G is dissolved in water to make 0.182 L of solution, and the osmotic pressure of the solution at 25C is found to be 0.867 mbar. Calculate the molecular mass of immunoglobulin G.
The solubility of oxygen gas at 50*C is 27.8 mg/L at an oxygen pressure of 1.00 atm. The solubility of nitrogen gas at 50*C is 14.6 mg/L at a nitrogen pressure of 1.00 atm. Assume that the air above the water contains an oxygen partial pressure of..
