At STP, a container has 1 mole of Ar, 2 moles of `CO(2)`, 3 moles of `O_(2)` and 4 moles of `N_(2)`. Without changing the total pressure if one mole of `O_(2)` is removed, the partial pressure of `O_(2)` :

A

450

B

760

C

152

D

380

Text Solution

Verified by Experts

The correct Answer is:
C
Total moles `=0.3+0.1+0.1`
=0.5
`Po_(2)=(0.1)/(0.5)xx760=(1)/(5)xx760`
`=150mm Hg`
