Oxygen molecule has the formula `O_(2)` while sulphur has `S_(8)` - explain.

Oxygen molecule has the formula O_(2) while sulphur is S_(8) . Why ?

Explain the following: (a) Oxygen molecule has formula O_2 while sulfur has S_g . (b) CIF_3 exists whereas FCl_3 does not.

The formula of sulphur molecule is

Oxygen exists as O_2 while sulphur exists as S_8 ,although they belong to same family. Explain.

(a) Define gram molecular mass of a substance. How much is the gram molecular mass of oxygen ? (b) If sulphur exists as S_(8) molecules, calculate the number of moles in 100 g of sulphur. (S = 32 u)
