160 ml of a gas are collected over water at `25^(@)C` and 768.8mm Hg. If aqueous tension at `25^(@)C` is 23.8 mm Hg, then pressure of dry gas at `25^(@)C` is `1:29 PM`

A

76.8mm Hg

B

760 mm Hg

C

721.2mm Hg

D

600 mm Hg

Text Solution

Verified by Experts

The correct Answer is:
C
Pressure of dry gas
= Pressure of gas collected over water -Aqueous tension
`= 745-23.8 = 721.2 mm`
