Question

80.0 liters of oxygen is collected over water at 50.0 °C. The atmospheric pressure in the room is 96.00 kPa. What is the partial pressure of the oxygen?

Answer 1

Answer: 83.656 kpa

Explanation:

Use Dalton's law of partial pressures which states that the total pressure of a combination of gases is equal to the sum of the partial pressures of the constituent gases.

So we have,

P(total) = P(oxygen) + P(water vapour)

96.00 kpa = 12.344 + P(oxygen)

P(oxygen) = 83.656 kpa
