Answer:
436.8 mmHg.
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pₜ) = 0.93 atm
Pressure of N₂ (Pₙ₂) = 270 mmHg
Pressure of O₂ (Pₒ₂) =?
Next, we shall convert the total pressure to mmHg . This can be obtained as follow:
1 atm = 760 mmHg
Therefore,
0.93 atm = 0.93 × 760 mmHg / 1 atm
0.93 atm = 706.8 mmHg
Finally, we shall determine the pressure of the O₂. This can be obtained as follow:
Total pressure (Pₜ) = 706.8 mmHg
Pressure of N₂ (Pₙ₂) = 270 mmHg
Pressure of O₂ (Pₒ₂) =?
Pₜ = Pₙ₂ + Pₒ₂
706.8 = 270 + Pₒ₂
Collect like terms
706.8 – 270 = Pₒ₂
436.8 = Pₒ₂
Pₒ₂ = 436.8 mmHg
Thus, the pressure of O₂ is 436.8 mmHg
