Emperical formula of compound is SF(4). ...

Emperical formula of compound is `SF_(4)`. At `27^(@)C` 0.1gm of gaseous compound occupies a volume of 22.2 ml and exert a pressure 1 atm. What is molecular formula of gas.
[Take R=0.08atm lit `k^(--1) "mol"^(-1)`]

A

`SF_(4)`

B

`S_(2)F_(8)`

C

`S_(3)F_(12)`

D

`S_(4)F_(6)`

Text Solution

Verified by Experts

PV=nRT M.F= `(SF_(4))_(x)`
`(1.02)xx22xx10^(-3)`
`(0.1)/((108)x)xx0.0821xx293`
`x=(0.1xx0.0821xx293)/((108)(1.02)(22.1)xx10^(-3))=1`
M.F. `=SF_(4)`
