Hemoglobin is the protein that transports oxygen in mammals. Different species of mammals have slightly different forms of hemoglobin. One form of hemoglobin is 0.324% Fe by mass, and each hemoglobin molecule contains four iron atoms. Calculate the molar mass of this form of hemoglobin. Make sure to include units of g/mol. Enter your answer in Scientific notation with three significant figures. The Scientific notation for 2 x 10-4 would be written as 2E-4.
