  • C. 65,000 times
  • D. 69,000 times

Explanation

Correct option is B. Hemoglobin is the oxygen carrying molecule in blood. It consists of an iron-containing heme together with 4 globin subunits to form the overall hemoglobin molecule, with molecular weight of about 64.500. Hemoglobin is 68,000 times heavier than hydrogen.

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
