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

21 mm Hg

751 mm Hg

0.96 atm

1.02 atm

Text Solution

Verified by Experts

The correct Answer is:

The pressure of dry `O_(2)` gas `= 751 - 21`
`= (730)/(760) mm = 0.96 atm`
