Immunoglobulin G(IgG), formerly called gamma globulin, is a principle antibody in blood serum. A 0.457 gram sample of immunoglobulin G is dissolved in water to make 0.123 L of solution, and the osmotic pressure of the solution at 25C is found to be 0.614 mbar. Calculate the molecular mass of immunoglobulin G.

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
