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.
