A55 kg women 7.5 x 10 - 3 all off hemoglobin ( molar mass = 64,456 g/mol) in her blood. how many hemoglobin
molecules is this? what is this quantity in grams?

The number of molecules of hemoglobin are and the mass is 483.42 g

Explanation:

We are given:

Moles of hemoglobin =

According to mole concept:  

1 mole of compound contains number of atoms

So, moles of hemoglobin compound will contain = number of molecules.

To calculate the mass of hemoglobin, we use the equation:

Molar mass of hemoglobin = 64456 g/mol

Moles of hemoglobin =

Putting values in above equation, we get:

Hence, the number of molecules of hemoglobin are and the mass is 483.42 g
