A compound contain 3.4% by weight of sulphur, the minimum molecular wt of compound is:-

A

941.76

B

944

C

945.27

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
`% wt = ("Atomic "xx"Atomic wt" )/"(molecular wt)"xx100`
If minimum molecular wt is to be found then take atomicity = 1
`3.4 = (1xx32xx100)/"(min. molecular wt )"`
`rArr` Minimum molecular wt = 941.176
