Immunoglobulin G (IgG), formally called gamma globulin, is a principal antibody in blood serum. A 0.678 g sample of immunoglobulin G is dissolved in water to make 0.136 L of solution, and the osmotic pressure of the solution at 25 degrees C is found to be 0.823 mbar. Calculate the molecular mass of immunoglobulin G.
