The molecular weight of hemoglobin is 64,500 daltons (= g mol-1).

a. how much oxygen can be bound per g of hemoglobin? express the values as ml per g of hemoglobin, where ml is the volume of o2. r =0.082 l atm mol-1 ok-1, ok =273 + oc. the molar volume of o2 is given as v = nrt/p where p = 1 atm and n= 1 mol; (hint: 1.0 mol x 0.082 l atm mol-1 ok-1 x 273.2 ok / 1 atm = 22.4 l mol-1)

Thus, one gram of Hemoglobin carries 1.389 mL of oxygen.

Explanation:

Each hemoglobin molecules carries 4 oxygen molecules.

Given that the molar mass of  hemoglobin = 64,5000 g/mol

1 gram of  hemoglobin =

Now, no of moles of oxygen carried in 1 mole of  hemoglobin =

= moles

assuming the oxygen is to be an ideal gas; then:

PV = nRT

Given that :

Then V =

V = 1.389 mL

Thus, one gram of Hemoglobin carries 1.389 mL of oxygen.
