Question

A mixture of nitrogen gas and oxygen gas has a total pressure of 123.5 kPa. If the
nitrogen gas has a partial pressure of 104.5 kPa, what is the partial pressure of the
oxygen gas?
6
Ptotal= P1 + P2

Answer 1

Answer: 19kpa

Explanation:

The total pressure of a mixture of gases is the sum of the partial pressure exacted by the individual gases.

P total = P X + P Y

From the question above:

P total = P .nitrogen + P. oxygen

123.5kpa = 104.5kpa + P. Oxygen

P. Oxygen = 123.5kpa - 104.5kpa

= 19kpa
