Answer 1

Answer:

Hope it helps you...

Explanation:

We know that,

m = dv

Where m is mass, d is density, and v is volume.  In this case, you are looking for mass, you have volume.  So you need to know the density of air.

As is turns out, the approximate density of air at sea level is 1.2 kilograms per cubic meter.

First, we must find the the volume of the room, which you get by multiplying its dimensions.  That tells us that the room is 30 m^3.  Now we can plug in the numbers

m = 30 * 1.2

which gives us

m = 36 kilograms.

So, the air in your room weighs approximately 36 kg.
