A sample of `O_(2)` gas is collected over water at `23^(@)C` at a barometric pressure of 751 mm Hg (vapour pressure of water at `23^(@)C` is 21 mm Hg). The partical pressure of `O_(2)` gas in the sample collected is

A

21 mm Hg

B

751 mm Hg

C

0.96 atm

D

1.02 atm

Text Solution

Verified by Experts

The correct Answer is:
C
Pressure of `O_2` (dry) = 751–21 = 730 mm Hg
` = 730/760 = 0.96atm .`
