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

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

D

`0.25 atm`

Text Solution

Verified by Experts

The correct Answer is:
C
`(p_(O_(2)))/(p_("total")) = (n_(O_(2)))/(n)`
`p_(O_(2)) = 4/5 xx 1` atm
`= 0.8atm = 0.8 xx 101325 Nm^(-2)`
`= 8 xx 10^(4) Nm^(-2)`
