An oleum sample contains `10 g SO_(3)` and `15 g H_(2) SO_(4)`
Answer the following questions on the basis of above information :
`%` labelling of oleum sample is .

A

`27.25%`

B

`106%`

C

`109%`

D

`118%`

Text Solution

Verified by Experts

The correct Answer is:
(C )
`%` labelling of oleum sample `= (100 + x) %`
`{:(SO_(3),+,H_(2)O,rarr,H_(2)SO_(4)),(10g,,,,),(1//8mol,,1//8mol,,):}`
`2.25g`
`:. %` labelling `= (100 + 9) % = 109 %` .
