A cylinder contains 0.3 moles of `N_(2)`, 0.1 mole of `O_(2)` and 0.1 mole of helium. If the total pressure is one atm, what is the partial pressure of oxygen in mm Hg:-

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`
