Question

In a mixture of two gases, the partial pressure of methane (CH4) is 0.175 atm and the partial pressure of oxygen is 0.250 atm. What is the mole fraction of methane and oxygen in the mixture?​

Answer 1

Explanation:

For a, we can use the mole fraction equation: pressure of the individual gas/sum of the pressures of all gases = mole fraction The sum of the pressures of all gases is 0.175 0.250 = 0.425 So for methane (CH4) = 0.175/0.425 = 0.412 (remember to round to three significant digits) and for oxygen gas: 0.250/0.425 = 0.588 .

Answer 2

Answer:

0.412 and 0.588

Explanation:

The sum of all pressure of gases is

• 0.175+0.250=0.425

For methane(CH4)

1. 0.175/0.425=0.412

For oxygen:-

1. 0.250/0.425=0.588
