Get a vacuum chamber. Get all the air out of it, and weight it. This is the true weight of just the vacuum chamber. Fill it with air, and then weight it again. Subtract the new weight from the initial weight to get the mass of the air contained within the chamber. Find the volume of the chamber as well.
density= mass/ voume. Hope it heelpss(:

The definition of density is: (mass) divided by (volume). It's going to be pretty tough to determine the sample's density if you don't figure out some way to find its mass.
Density can be used to determine buoyancy. To find out of something will float or sink, density is a good way to make a prediction.
No, you will also need some way to determine the volume of the object.
You cannot. You can determine the third variable if two are given but not determine two when given only one. You have to find some other way to first determine volume or density.
Knowing the mass doesn't tell you the volume. They're related by the quantity called the "density" of a sample. So if, along with the mass, you also know the density, then the volume is (mass) divided by (density). But if you only know the mass, there's no way to calculate the volume. Equal masses of air and water have very different volumes.
i think the way you can determine the number of seeds in an a apple is of its density
The exact same way you would propose anyone you'd want to propose.
Yes, humidity can affect air density. Moist air is less dense than dry air because water vapor molecules are lighter than nitrogen and oxygen molecules. Therefore, higher humidity levels can lead to lower air density.
= What is low air density? = well, high or low are relative concepts. Normally the standard air density of the air is defined as the density of the air at 15ºC and at sea level pressure (standard conditions), what give a value of 1,225kg/m3. This way, we can talk about high or low air density related to the standard value. Air density depends on temperature and pressure. The colder the temperature the higher the density is, and the higher the height in the atmosphere the lower the density becomes. In the Everest peak, e.g., air density can be lower than 0,5. Meanwhile in the Antarctica (at sea level) the density could reach values higher than 1,5.
The same way you determine the density of any other object. Divide the mass by the volume. Add: density = mass/volume = 5g/1mL = 5g/mL = 5g/cm3* *1mL = 1 cm3
