Question

The number if Fe atoms in 100g Haemoglobin if it contains 0.33% Fe.​

Answer 1

Answer:

Mass of hemoglobin = 100 g

Mass of iron atoms =(

100

0.33

)×100=0.33g

56 g of iron contains = 1 mole of iron or 6.033×10

23

atoms

0.33g of iron contains =moles=

56

0.33

=5.89×10

−3

Number ofFe atoms=5.89×10

−3

×6.02×10

23

=3.5442×10

21

atoms of Fe
