If nitrogen gas is collected over water at 20 o C and the total pressure of the gas in the collection vessel is 200 kPa, what is
the pressure of dry nitrogen gas?
1 answer:
Answer:
Explanation:
pressure of dry nitrogen gas at 20° = Partial pressure of nitrogen and partial pressure of water at that temperature .
The pressure of dry nitrogen gas= total pressure - vapour pressure of water at 20°C
= 200 k Pa - 2.34 k Pa
= 197.66 kPa.
