- A1 mole of benzene and 1 mole of ethene contain the same number of atoms.
- B1 mole of benzene and 1 mole of ethene both have a volume of $24\,\text{dm}^3$ at room temperature and pressure.
- CBoth benzene and ethene have the same empirical formula.
- DThe number of carbon atoms in $0.5$ moles of ethene is equal to the Avogadro constant.
