Self Test: Molecular Equilibrium Total 100 80 O, combined with HD . 1. In humans, the average hemoglobin concentra tion is 16 g/100 ml. of blood with approximately 1.50 * 10 hemoglobin molecules in 100 ml of whole blood. Each hemoglobin molecule can carry 4 oxygen molecules a. What is the approximate molar mass of hemo globin? 860 Hb saturation o, concentration mL per 100 mL 40 20 2 0 Dissolved 0 40 60 80 PO, mmHg 20 100 b. How many possible binding sites for oxygen are contained in 100 mL of blood? c. How many O molecules can be carried by 100 mL of blood if the partial pressure of O, is 50 mmHg 2. Explain in detail the effect raising the temperature has on the equilibrium and the equilibrium constant of an exothermic reaction
