Sulfur molecules exist under various conditions as s2, s, s4, s6, and s8. which of the following statements are true?
a) the number of sulfur atoms in one mole of each of these molecules is the same.
b) the mass of one mole of each of these would be the same.
c) the mass of sulfur in one mole of each of the molecules is the same.
d) the number of molecules in one mole of each would be the same.

d) The number of molecules in one mole of each would be the same.

Explanation:

All the molecules given have different numbers of atoms of sulfur, S has 1 atom, S₂ has two atoms, S₄ has four atoms, S₆ has six atoms and S₈ has eight atoms.

The mass of 1 mol of these molecules depends on the number of sulfur atoms because the mass will be equal to the molar mass of sulfur multiplied by the number of atoms. So, they are different.

The mass of sulfur in one mole of the molecule also depends on the molar mass and the number of sulfur atoms. The molecules only have sulfur, so their molar mass will be the mass of sulfur in 1 mol.

The number of molecules in 1 mol is always 6.02x10²³, which is the Avogadros' number, and it doesn't depend on the molecule either its composition, so it's the same for all the molecules.
