203.2 centimeters.
This is because 1 inch = 2.54 centimeters which means multiply 80 inches X 2.54 = 203.2 centimeters.

A room is filled with saturated moist air at 25°C and a total pressure of 100 kPa. If the mass of dry air in the room is 100 kg,

ANTONII [103]

Answer:the mass of water vapor is=d. 2.04 kg

Explanation:

The humidity ratio by mass is given as

x = mw / ma (1)

where

mw = mass of water vapor

ma = mass of dry air

And also humidity ratio by pressure by Ideal Gas Law is given as

x = 0.62198 pw / (pa - pw) (2)

where

pw = partial pressure of water vapor in moist air

pa = atmospheric pressure of moist air

Equating both equation we have that

Humidity ratio = 0.62198 pw / (pa - pw)= mw / ma (3)

From the from the water table at 25°C,

water vapor partial pressure = 23.8 torr

1 atm =760 torr.

1 atm = 101.325 kPa,

So, 760 torr =101.325 kPa,

Therefore 23.8 torr =3.173kPa

Humidity ratio = 0.62198 pw / (pa - pw)= mw / ma

0.62198 x 3.173 / (100-3.173)= mw / 100

1.9736 /96.827=mw/100

0.0204=mw/100

mw=2.04kg
