Get all the air out of it, and weight it. This is the true weight of just the vacuum chamber.
To determine the density of air, one can use the ideal gas law equation, which relates the density of a gas to its temperature and pressure. By measuring the temperature and pressure of the air, one can calculate its density using the formula: density pressure / (gas constant temperature).
The density of air can be determined by measuring its mass and volume, and then dividing the mass by the volume. This calculation gives the density of air in units such as kilograms per cubic meter.
Air density can be determined by measuring the mass of a known volume of air and then calculating the density using the formula: density mass/volume. This can be done using instruments such as a balance and a container of known volume.

Air density determines how much mass is present in a given volume of air. It affects things like buoyancy, pressure, and the ability of objects to move through the air, such as airplanes and birds. Changes in air density can impact weather patterns and climate.
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.
To calculate the percent of air content in a soil sample, you need to determine the volume of air in the soil and divide it by the total volume of the sample. This can be done by measuring the bulk density of the soil and the particle density, then subtracting the particle density from the bulk density to get the volume of air. Finally, divide the volume of air by the total volume and multiply by 100 to get the percentage.
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.
