Hemoglobin (C2952H4654N8120 832S8Fe4) is the oxygen
Chapter 3, Problem 119P(choose chapter or problem)
Hemogoblin \((\mathrm{C}_{2952} \mathrm{H}_{4654} \mathrm{N}_{812} \mathrm{O}_{832} \mathrm{S}_{8} \mathrm{Fe} _{4}\)) is the oxygen carrier in blood.
(a) Calculate its molar mass.
(b) An average adult has about 5.0 L of blood. Every milliliter of blood has approximately \(5.0 \times 10^{9}\) erythrocytes, or red blood cells, and every red blood cell has about \(2.8 \times 10^{8}\) hemoglobin molecules. Calculate the mass of hemoglobin molecules in grams in an average adult.

ANSWER:
Step 1 of 4
Hemoglobin 
(a)
Here, we are asked to calculate the molar mass of Hemoglobin.
Molar mass of C = 12.0107 g/mol.
Molar mass of H = 1.0079 g/mol.
Molar mass of N = 14.0067 g/mol.
Molar mass of O = 15.999 g/mol.
Molar mass of S = 32.065 g/mol.
Molar mass of Fe = 55.845 g/mol.
