Question

haemoglobin contains 0.33 of iron by weight . molecular weight of haemoglobin is 67200.how many iron atoms are present in one molecule of haemoglobin.

Answer 1

hope it was helpful plz mark me as brainlist

Answer 2

Answer:

The answer is =4.

Explanation:

Hemoglobin is a protein in your red blood cells that brings oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues around to your lungs. If a hemoglobin test indicates that your hemoglobin level stands lower than normal, it means you keep a low red blood cell count (anemia).

In $100 \mathrm{~g}$ hemoglobin, the mass of iron $=0.33 \mathrm{~g}$

Therefore $\ln 67200 \mathrm{~g}$  hemoglobin, mass, or iron

$=\frac{67200 \times 0.33}{100}$

$=672 \times 0.33 \mathrm{~g}$

Therefore The number of Fe atoms in one Hb molecule

$=\frac{672 \times 0.33}{56}$

=4.
