A DNA molecule is small in actual size but contains an enormous number of atoms. Surprisingly, the molecule is made up of atoms of just five different elements. Study Figure $1.19$ and identify which elements those are.
A single molecule has a mass of $7.31 \times 10^{-23} \mathrm{g}$. Provide an example of a real molecule that can have this mass. Assume the elements that make up the molecule are made of light isotopes where the number of protons equals the number of neutrons in the nucleus of each element.
