Calculate the pressure of the dry gas collected over water at 10 degree celcius and 750mmHg. Given that the vapour pressure of water at 10 degree celcius is 20mmHg
Ptotal = p(drygas) + pH2O
750 = pdrygas + 20
Solve for p dry gas.
730
Explain more better i dont understand
To calculate the pressure of the dry gas collected over water, we need to subtract the vapor pressure of water at that temperature from the total pressure.
In this case, the total pressure is given as 750 mmHg, and the vapor pressure of water at 10 degrees Celsius is given as 20 mmHg.
So, the pressure of the dry gas collected over water can be calculated as follows:
Pressure of dry gas = Total pressure - Vapor pressure of water
Pressure of dry gas = 750 mmHg - 20 mmHg
Pressure of dry gas = 730 mmHg
