You multiply the volume of the desired object - the inside of your room, perhaps - by the density.
1m3 weighs 1.2Kg true
Density of substance = mass of substance / volume mass of substance = density x volume
As the air bubble increases in volume, its mass remains constant. Because the mass remains constant but volume increases, density will decrease.
The space between the molecules in the air mixture increases which decreases the density of the air. As the density decreases, the mass of warm air rises.
Air density is the mass of air per unit volume, which changes by temperature, humidity, and elevation. Changes in air density will change its pressure. At mean sea level and 20°C, air has a density of approximately 1.2 kg/m3.
The three properties of air are weight, mass, and density.
Volume = mass / Density Mass = Volume * Density Density = Mass / Volume
The density of water is about 1000 kg/m3 and the density of air is about 1 kg/m3. Using only your own everyday knowledge quantified (and your personal measuring sticks), estimate the mass of blood that is pushed out of the heart in each heartbeat and the mass of air that is pushed out of your lungs with each breath.
the air density is 40,000
mass,density,and pressure. :)
its density / mass
Density = Mass / Volume. So, if your volume stays the same, and there is a greater mass of air, then the density goes up.
That question doesn't mean anything, mass is mass. If you are asking which has a greater mass per unit volume, also known as density, then the air will have a lower density than clay.

Air has density and pressure because it has mass.Even though it doesn't seem like air has any mass.Yes,air has mass.
The basic equation for density is: density = mass/volume To solve for volume: volume = mass/density = 9.20g/1.15g/L = 8.00L
