A gas is collected by water displacement at 25 degrees celsius.(the vapor pressure of water at that temperature is 24mmhg.if the atmospheric pressure is 800mmhg.what is pressure of the dry ice
Ptotal = pdry ice + pH2O
Substitute total land pH2O, then solve for pdry ice.
To find the pressure of the dry ice, we need to subtract the vapor pressure of water at that temperature from the atmospheric pressure.
The vapor pressure of water at 25 degrees Celsius is given as 24 mmHg. The atmospheric pressure is given as 800 mmHg.
So, the pressure of the dry ice can be calculated using the formula:
Pressure of dry ice = Atmospheric pressure - Vapor pressure of water
Pressure of dry ice = 800 mmHg - 24 mmHg
Pressure of dry ice = 776 mmHg
Therefore, the pressure of the dry ice is 776 mmHg.
