Answer:
- Mole fraction of SO₃ : 0.135
- Partial pressure SO₃ = 0.128 atm
Explanation:
Let's find out the mole fraction to know, what we were asked.
Mole fraction = Moles of a gas / Total moles
Mole fraction can also corresponds to Pressures, like this:
Mole fraction = = Partial pressure of a gas / Total pressure
And this values are the same
The total moles of gases are:
Moles of SO + Moles of O₂ + Moles of SO₃ =
26 + 83 + 17 = 126 moles
Mole Fraction SO₃ = Moles of SO₃ / Total moles
17 / 126 = 0.135
This can be used to find out the partial pressure
Mole fraction = Partial pressure SO₃ / Total pressure
0.135 = Partial pressure SO₃ / 0.950 atm
0.135 atm . 0.950atm = Partial pressure SO₃
Partial pressure SO₃ = 0.128 atm
