Question

Dietary iron forms a 1:1 complex with hemoglobin (Hb), which is responsible for O2 transport in the body based on the following equation: Hb+4O2→Hb(O2)4 How many moles of oxygen could be transported by the hemoglobin complex formed from 6 mg of dietary iron? [ Anemia-A Limiting Reagent Problem? p. 172] Express your answer to two significant figures and include the appropriate units.

Answer 1

l Hb + 4o. - Since one mole 4 mole of Og H6(0) of Hb can transport So let us find number of moles in 6 mg of Hb | wheree mole wt. of H8= 65000) > n = n (given wt) m (molit) moles of 6x10 3 g 65000 gl mol = 0.092 x 10-6 mol = 0.1X10 & No. of moles of og transported = 480.092x10-6 ay 4 X o Lx 10-6 = 0.4 x 10-6 mote AL
