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.
