Answer 1

Normal whole blood contains 12-18 g of hemoglobin per 100 mL and can carry up to 120 molecules of oxygen.

Step-by-step explanation:

Normal whole blood contains 12-18 g of hemoglobin per 100 mL.

Hemoglobin consists of four subunits, each of which contains one molecule of iron. Each subunit is arranged in a ring-like fashion, with an iron atom bound to the heme in the center. Hemoglobin can carry up to 120 molecules of oxygen.
