A 3.1 L sample of hydrogen <u>d. contains the same number of molecules</u>

as 3.1 L of carbon dioxide at the same temperature and pressure.

This is the fundamental principle of <em>Avogadro’s hypothesis</em>: equal volume of gases at the same temperature and pressure contain the same number of molecules.

The sample of carbon dioxide has a <em>greater mass</em>, a <em>greater number of atoms</em>, and a <em>greater density</em>, than the sample of hydrogen.
