What is the mass percent of iron in hemoglobin?

What is the mass percent of iron in hemoglobin?

0.25\%
Haemoglobin contains 0.25\% iron by mass. The molecular mass of haemoglobin is 89600. Calculate the number of iron atoms per molecule of haemoglobin.

How do you calculate the relative molecular mass of haemoglobin?

  1. In 5.04 L, the total mass of haemoglobin is 15 × (5.04 × 103 / 100) = 756 g.
  2. molar mass is 6.45 × 104 g mol-1, this corresponds to.
  3. moles of haemoglobin = mass / molar mass.
  4. = (756 g)/(6.45 × 104 g mol-1) = 0.0117 mol.
  5. As haemoglobin contains 4 Fe atoms, the number of moles of Fe is 4 × 0.0117.
  6. mol = 0.0469 mol.

How many moles of iron are present in 1mg of haemoglobin assuming a molecule of haemoglobin contains 4 Fe atoms?

So, the number of moles of iron in 1 mole of hemoglobin = mass of iron in hemoglobin / molecular mass of iron. Correspondingly 1 molecule of hemoglobin contains 4 atoms of Fe. So, the correct answer is “4”.

How many atoms does Haemoglobin have?

Each molecule has 64,500 times the weight of a hydrogen atom and is © 1964 SCIENTIFIC AMERICAN, INC Page 2 made up of about 10,000 atoms of hy drogen, carbon, nitrogen, oxygen and sulfur, plus four atoms of iron, which are more important than all the rest.

What is formula of Haemoglobin?

The molecular formula of haemoglobin is \[{C_{2952}}{H_{4664}}{N_{812}}{O_{832}}{S_8}F{e_4}\]. Additional information: The common types of normal haemoglobin are Haemoglobin \[A\], Haemoglobin \[F\], Haemoglobin \[A2\]. Low haemoglobin level is an indication of anaemia.

What is the molecular mass of hemoglobin?

The average molar mass of an entire mammalian hemoglobin molecule is ≈64,500.

How many moles of iron are present in 1mg of haemoglobin?

1 mole of hemoglobin contains 4 X (moles) of iron. 0.5 mole of hemoglobin contains 4 X (0.5 moles) of iron = 2.00 moles of iron.

What is the minimum molar mass of hemoglobin?

What is the minimum possible molar mass of hemoglobin? The actual molar mass of hemoglobin is about 65,000 g.
