Question

39. Sulfur molecules exist under various conditions as S8, S6. S4, S2, and S. a) Is the mass of one mole of each of these moles the same? b) Is the number of molecules the same? c) Is the mass of sulfur in one mole of each these molecules the same? d) Is the number of atoms of sulfur in one mole of each of these molecules the same?

Answer 1

a) no

Molar mass S8 = 256.528 g/mol

Molar mass S6 = 192.296 g/mol

Molar mass S4 = 128.264 g/mol

Molar mass S2 =64.132 g/mol

Molar mass S = 32.066 g/mol

b) 1 mole of each has the same number of molecules

c) No as in the question a

d) no

atoms S in 1 mole of S8 = 6.02 x 10^23 x 8

atoms S in 1 mole of S6 = 6.02 x 10^23 x 4

and so on

Answer 2

a) No. They all have different amount of Sulfur atoms so the mass must be different. Use your periodic table to figure out there molar masses and you'll see.

b) Yes, one mole will contain one mole of molecules for each of those

c) No, basically the same thing as question a, they all have different masses so one mole of them will have different masses of sulfur.

d) No, S8 has 8 sulfur atoms, S4 has 4 sulfur atoms in a single molecule so they have different amounts of atoms.
