Chapter 22, Problem 22.36QP

Interpretation Introduction

Interpretation:

The minimum possible molar mass of the haemoglobin has to be calculated.

Concept introduction:

The mass percentage of a compound can be calculated with the calculated mass of the compound to the total mass of the compound.

$\text{Mass}\text{percent(in}\text{\%)=}\frac{\text{Mass}\text{of}\text{compound(in}\text{g)}}{\text{Total}\text{mass(in}\text{g)}}$

Minimum mass of hemoglobin $\text{1}\text{.6}\times {\text{10}}^{\text{4}}g$

Haemoglobin must contain four $\text{Fe}$ atoms per molecule for the actual molar mass to be four times the minimum value calculated.
