A gas is collected over water at 25C and the volume inside the inverted container is equalized with the water level outside the container. The barometric pressure is 749.7 torr and the vapor pressure of water is 23.8 torr at 25C. Calculate the dry pressure of the gas.

Respuesta :

Answer:

The Dry pressure of the gas = 725.9  torr

Explanation:

Total barometric pressure = 749.7 torr

Vapour pressure of water =  23.8 torr

The total pressure is = Vapour pressure of water + Dry pressure of the gas

749.7 = 23.8 +  Dry pressure of the gas

Dry pressure of the gas = 749.7 - 23.8

Dry pressure of the gas = 725.9  torr

Therefore the Dry pressure of the gas = 725.9  torr
