Chapter 3, Problem 92AE
Interpretation Introduction
Interpretation: The molar mass of hemoglobin is to be calculated.
Concept introduction: The mass percentage is used as one of the ways to estimate the composition of a compound. It expressed in terms of percentage by mass of elements that constitute that compound. The formula for mass percent involves the ratio of element’s mass in one mole of compound to molar mass of compound. The final value of mass percent is obtained by multiplying this ratio with
