Final answer:
One mole of C₆H₁₂ contains twelve moles of hydrogen atoms, as the chemical formula shows that there are twelve hydrogen atoms per one molecule of the compound.
Step-by-step explanation:
The question involves understanding the concept of moles and the stoichiometry of a chemical formula. In the compound C₆H₁₂, one mole of the compound contains six moles of carbon atoms and twelve moles of hydrogen atoms. This is because the chemical formula indicates that in one molecule of C₆H₁₂, there are six carbon atoms and twelve hydrogen atoms.
Therefore, one mole of C₆H₁₂ would contain twelve moles of hydrogen atoms, since the subscript next to hydrogen in the molecular formula represents the number of hydrogen atoms in one molecule of the compound.
