Answer;
= 64561.95 g/mole
Explanation;
mass of Fe in 100g = .346g
= .346 / 55.8452 moles
= 0.0061957 moles
These represent 4 moles of Fe in the molecule so moles of hemaglobin
= 0.0061957/4
= 0.0015489 moles
these are in 100 g so mass of 1 mole = 100 / 0.0015489
= 64561.95 g / mole
molar mass of hemoglobin = 64561.95 g/mole

Answer:
Luster: Silicon for example appears lustrous, but is not malleable or ductile (it is brittle - a characteristic of some nonmetals). It is a much poorer conductor of heat and electricity than the metals.8 May 2021

Answer:
O atom requires 2 electrons to achieve octet structure and in this structure, it is only bonded to one H atom hence only obtaining an additional valence electron. Without a octet structure, the molecule is unstable hence this structure is incorrect. The correct structure should be H-O-H.
