Answer:

Molar mass of hemoglobin is 64380.4 g/mol

Explanation:

Percentage of Fe calculated from the equation

%Fe = 4×molar mass of Fe/molar mass of hemoglobin.(4 because hemoglobin contain 4 Fe atoms)

Molar mass of hemoglobin is =4×molar mass of Fe / % Fe

=4×55.85/.00347

=64380.4 g/mol.

The molar mass of hemoglobin is 64380.4 g/mol.

Since Hemoglobin is 0.347% by mass,

here we have to determine the percentage of Fe

%Fe = 4×molar mass of Fe/molar mass of hemoglobin

So,

The molar mass of hemoglobin is

=4×molar mass of Fe / % Fe

=4×55.85/.00347

=64380.4 g/mol.

hence, The molar mass of hemoglobin is 64380.4 g/mol.
