Question

13. Myoglobin stores oxygen for metabolic process in
muscle. Chemical analysis shows that it contains
0.32% Fe by mass. If there is one Fe atom per
molecule of myoglobin, what is the molar mass of
myoglobin? (at. mass of Fe = 56 u]
(1) 1.75 x 10^4 g/mol (2) 3.5 x 10^5 g, mol
(3) 1 x 10^4 g/mol (4) 2.5 x 10^5 g/mol​

Answer 1

Answer:

a

Explanation:

let x u be the mass of myoglobin

since each myoglobin comtain 1 atom

0.32×10^-2= 56/x

x=56/(32×10^-4)

x= 1.75×10^4
