Equal weights of methane and oxygen are mixed in an empty container at `25^(@)C`. The fraction of the total pressure exerted by oxygen isA. `(2)/(3)`B. `(1)/(3) xx (273)/(298)`C. `(1)/(3)`D. `(1)/(2)` |

Answer» Correct Answer - C Let the masses of methane and oxygen are `w g` each. Mole fraction of oxygen `= ((w)/(32))/((w)/(32) + (w)/(16)) = ((1)/(32))/((1)/(32) + (1)/(16)) = ((1)/(32))/((3)/(32)) = (1)/(3)` Let the total pressure be `P`. The pressure exterted by oxygen (partial pressure) `= X_(O_(2)) xx P_("total") = P xx(1)/(3)` |
