You can put this solution on YOUR website! find the mass and weight of the air in a living room at 20 degree Celsius with 4.0 m x 5.0 m and a ceiling 3.0 m high. what are the mass and weight of an equal volume of water?
-------------
The volume is the product of the dimensions = 60 cubic meters.
60 m^3 * 1000 kg/m^3 = 60000 kg of water.
--------------
You'll have to spec the density of air.
You can put this solution on YOUR website! v = 4 * 5 * 3 = 60 cu.m
---
density of air at 20 degrees C = 1.2041 kg/cu.m
http://en.wikipedia.org/wiki/Density_of_air
---
ma = d * v
ma = 60 * 1.2041
ma = 72.246 kg
---
density of water at 20 degrees C = 998.207 kg/cu.m

---
mw = d * v
mw = 60 * 998.207
mw = 59,892.42 kg
