Question 809320: 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.
Answer by TimothyLamb(4379)   (Show Source):
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 = mass 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 = mass of water
mw = d * v
mw = 60 * 998.207
mw = 59,892.42 kg
