Myoglobin stores oxygen for metabolic processes in

muscle. Chemical analysis shows that it contains

0.34 percent Fe by mass. What is the molar mass of

myoglobin? (There is one Fe atom per molecule.)

Verified Answer :

Mass of Fe / Total mass x 100 = Percentage iron
0.34 = 56/Total mass x 100
Total mass = 16,470 g/mol

Answer:

16,426.47 g/mol is the molar mass of  myoglobin.

Explanation:

Percentage of iron in myoglobin = 0.34%

Molar mass of iron = 55.85 g/mol

Number of iron atom per molecule = 1

Molar mass of myoglobin = M

\(\% \text{of iron}=\frac{\text{Mass of iron}}{\text{Molar mass of myoglobin }}\times 100\)

\(0.34 \%=\frac{55.85 g/mol}{M}\times 100=16,426.47g/mol\)

16,426.47 g/mol is the molar mass of  myoglobin.
