3.2 g of S is heated to occupy a volume ...

`3.2 g` of S is heated to occupy a volume of `780 ml` at `450^(@)C` and `723 mm` pressure. Formula of sulphure is

A

`S_(2)`

B

`S`

C

`S_(4)`

D

`S_(8)`

Text Solution

Verified by Experts

The correct Answer is:
D
`PV=(w)/(M)RT`
`(723)/(760)xx(780)/(1000)=(3.2)/(M)xx0.0821xx683`
`M=256`
`:.` Atomicity `=(256)/(32)=8`
