A mixture of dihydrogen and dioxygen at ...

A mixture of dihydrogen and dioxygen at one bar pressure contains 20% by weight of dihydrogen. Calculate the partial pressure of dihydrogen.

Text Solution

Verified by Experts

`%` of `H_(2)=20, %` of `O_(2)=80`
`n_(H_(2))=20/2=10, n_(O_(2))=80/32=2.5`
`x_(H_(2))=10/(10+2.5)=10/12.5=0.8`
`p_(H_(2))=x_(H_(2))xxP_(H_(2))^(0)=0.8xx1 "bar"=0.8 "bar"`
