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.
You can take a baggie and fill it with air...then you should measure the volume and mass of that and do it that way
water
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
You pop the bag open and capture the air
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.
The density of heated air is less than the density of cooler air.
The smoke from a given volume of air is collected on a preweighed paper filter; density is mass/volume.
subtract 0.0011 from the density in vac to get density in air.
subtract 0.0011 from the density in vac to get density in air.
-- 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.
Air has both density and pressure.
Pressure affects the density of air by increase of pressure increases the density
