<u>Answer:</u> The number of ions in one molecule of hemoglobin are 4.
<u>Explanation:</u>
According to mole concept:
1 mole of an element contains number of atoms.
We are given:
Mass of 1 mole of hemoglobin =
number of molecules have a mass of
So, 1 molecule of hemoglobin will have a mass of
It is also given that 0.33 mass % of hemoglobin has ions
So, mass of ions will be =
- To calculate the number of moles, we use the equation:
Given mass of iron ion =
Molar mass of iron ion = 55.85 g/mol
Putting values in above equation, we get:
1 mole of an element contains number of atoms.
So, moles of hemoglobin will contain =
Hence, the number of ions in one molecule of hemoglobin are 4.
