the pressure of a `1 : 4` mixture of dihydrogen and dioxygen enclosed in a vessel is one atmosphere. What would be the partial pressure of dioxygen ?

A

`0.8 xx 10^(5)` atm

B

`0.008 Nm^(-2)`

C

`8xx 10^(4) Nm^(-2)`

D

0.25 atm

Text Solution

Verified by Experts

The correct Answer is:
C
`x(O_(2))=(4)/(1+4)=0.8`
`p(O_(2))=1xx0.8atm`
`=0.8xx1.01325xx10^(5)Nm^(-2)`
`=8xx10^(4)Nm^(-2)`
