Good one! Density is usually found by weighing a sample of a material and measuring its volume, but how do you weigh a sample of air? As this is very likely a homework question (preparatory question for a lab?) I'll only give some useful hints.
If you want to weigh your cat on a bathroom scale but can't get her to stand still on it, you can weight yourself, then weigh yourself again while holding the cat; the increase is the cat's weight. If you've weighed yourself with the cat first, you can still weigh yourself without her and then her weight is the decrease. Get it? You can weigh something by removing it and computing the decrease.

A way to find the density of the air?
water
How can you find the mass of an air?
i can find the mass of the air by comparing the volume of unit vaccum (ie)1 unit of course with the 1 unit of volume of air and then can find its density by examining the intramolecular force in the air particles and then by formula, density= mass/volume its simple
How do you find the density of air in a potato bag?
You pop the bag open and capture the air
Is air density in Atlanta is more or less than the air density in Denver CO.?
Air density - at least, the average air density - pretty much depends on the altitude. I suggest you look up the altitude of both places (you can probably find it on the corresponding Wikipedia articles); the place with the lower altitude should have a greater air density.
How do you think the density of heated air compares to the density of cooler air?
The density of heated air is less than the density of cooler air.
How do you estimate the mass of air if the density of air is 1.3kg per m3?
To estimate the mass of air, you would use the formula: Mass = Volume x Density. If you have the volume of the air in cubic meters and the density of air in kg per cubic meter, you can multiply the two values to find the mass of the air.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
Does air have density and pressure?
Air has both density and pressure.
What is vapour density of air?
The vapor density of air is approximately 1, which means that the density of air is close to that of water vapor.
How does the density of the air affect pressure?
Pressure affects the density of air by increase of pressure increases the density
Is a chlorine atom denser than air?
Density is how tightly packed the molecules or atoms are, so you can't find the density of a single atom. But a group of chlorine atoms are denser than air.
How do you calculate density of air at NTP?
The density of air at NTP (Normal Temperature and Pressure) can be calculated using the ideal gas law equation, where density = pressure / (gas constant x temperature). At NTP, the pressure is 1 atm, temperature is 273.15 K, and the gas constant for air is 0.0821 L.atm/mol.K. Plug these values into the equation to find the density of air at NTP.
