Equal masses of methane and oxygen are mixed in an empty container at `25^(@)C`. The fraction of the total pressure exerted by oxygen is:A. `(2)/(3)`B. `(1)/(3)xx(273)/(298)`C. `(1)/(3)`D. `(1)/(2)` |
|
Answer» Correct Answer - C Suppose the equal mass of methane and oxygen `=w=1g` `"Mole fraction of oxygen"=(w//32)/(w//32+w//16)=(1)/(3)` Let the total pressure =p Pressure exerted by oxygen (partial pressure) `=x_(O_(2))xxP_("total")=Pxx(1)/(3)` |
