Question
A sample of a dry gas is collected over water at a temperature of 30 degrees Celsius when the barometric pressure reading is 742.0 mmHg. What is the partial pressure of the dry gas? A sample of a dry gas is collected over water at a temperature of 30 degrees Celsius when the barometric pressure reading is 742.0 mmHg. What is the partial pressure of the dry gas? A sample of a dry gas is collected over water at a temperature of 30 degrees Celsius when the barometric pressure reading is 742.0 mmHg. What is the partial pressure of the dry gas?Explanation / Answer
we know that,
Vapour pressure of water at 30oC is = 31.8 mmHg
742.0 = P (gas) + P (water)
742 = P (gas) + 31.8
P (gas) = 742.0 - 31.8
P (gas) = 710.2 mmHg
