Question

Haemoglobin contains 0.33% of iron . and i molecule of haemoglobin contains 2 fe atoms. find the molecular weight of haemoglobin

Answer 1

Explanation:

Molecular weight of one Fe atom = 56 g

Molecular weight of 2 Fe atoms = 56 * 2 = 112 g

% of element in = weight of element * 100

compound. Total weight

0.33 = 112 * 100

M

M = 112 * 100

0.33

M = 3.39 * 10^4.

I hope it will be helpful for you.
