Hemoglobin (C2952H4664N812O832S8Fe4, molar mass = 65,322.91 g/mol) is the oxygen carrier in blood. An average adult has about 5.0 L of blood. Every milliliter of blood has approximately 5.0x 109 erythrocytes, or red blood cells, and every red blood cell has about 2.8x108 hemoglobin molecules. Calculate the mass of hemoglobin molecules in grams in an average adult.
