Chemistry - Mole Concept Question with Solution | TestHub

The molar mass of different allotropes (S₈, S₆, S₄, S₂, S) varies because it depends on the number of atoms in each molecule. For example, the molar mass of S₈ is $8\times (atomicmassofS)$, while for S₂ it is $2\times (atomicmassofS)$. Therefore, statements A and D are incorrect. One mole of each species (S₈, S₆, etc.) contains Avogadro's number of that specific species, so statement B is incorrect. Only statement C is correct because one mole of each contains the same number of sulfur atoms if the amount of sulfur is considered.
