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. `0.8xx10^(5)` atmB. `0.008 N m^(-2)`C. `8xx10^(4) N m^(-2)`D. 0.25 atm

Answer» Correct Answer - C
Partial pressure of `O_(2)`=Mole fraction of `O_(2)`xxTotal pressure of mixture
`=(4)/(5)xx1 "atm"=0.8xx10^(5)" N "m^(-2)=8xx10^(4)" N "m^(-2)`.
