Equal weights of methane and oxygen are mixed in an empty container at . The fraction of the total pression exerted by oxygen is -
1 / 3
1 / 2
2 / 3
273 / 298
If X g of both oxygen and methane are mixed then,
According to law of partial pressure,
partial pressure of oxygen mole fraction x total pressure
