Question

Equal masses of methane and oxygen oxygen are mixed in a container at 25 degree celsius fraction of the total pressure exerted by oxygen is

Answer 1

Answer:

2/3

Explanation:

let mass 'm' of each is added and the total pressure be 'p'

No. of moles of CH4=m/16

No. of moles of O2=m/32

mile fraction of O2=2/3

Pressure exerted by O2=total pressure×mole fraction of O2=(2/3)p
