It is difficult to weigh air, since air has a buoyancy that is exactly equal to its own weight (being surrounded by more air) - sort of like trying to weigh water while you are underwater. However, if you had a vacuum chamber in which you could work (wearing a spacesuit so you could breathe) then you could weigh air, inside a container (you would also have to weight the container separately, of course). A triple beam balance is sensitive enough for this job, if you use a large container.
Alternatively, you could weigh a light weight can, and then evacuate it and weigh it again. It will weigh less by the quantity of air excluded. But it is important that the can remains the same shape after evacuation, but your vacuum need not be particularly good for a reasonable measurement.
The mass of dry air is approx 0.0012 grams per cm3. Or about 1.2kg per m3. (check my math.)
What else can I help you with?
How can one determine the air density?
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.
Predict the mass of the bag with air?
The mass of the bag with air will be the sum of the mass of the bag itself and the mass of the air inside it. The mass of the air can be estimated by knowing the dimensions of the bag and the density of air at the given conditions.
When a spring balance holding a mass is allowed to fall freely what reading will it show?
When a spring balance holding a mass is allowed to fall freely, it will momentarily show zero reading as the force of gravity is no longer acting on the mass. Once the mass reaches its terminal velocity, the reading may fluctuate due to air resistance and other factors.
What the equipment that can be used to measure density of a material of the Archimedes principle.?
A common equipment used to measure the density of a material based on Archimedes' principle is a density balance or a hydrostatic balance. This equipment calculates the density by comparing the mass of the object in air to its apparent mass when submerged in a fluid. By measuring the buoyant force acting on the object, the density can be accurately determined.
How do calculate density for an irregularly shaped object?
1.Take a triple beam balance to find the weight 2.Then take a graduated cylinder a fill it about half way up with water 3.Measure how much water is in the container 4.Put your irregular shape in the water 5.Measure the water now 6.Subtract the difference 7.Then take your weight (in grams) divide by your volume (the difference of the water) AND THAT IS YOUR DENSITY
How do you know air has mass?
my science class did an experiment, we used a triple beam balance, a balloon, and a piece of tape. we measured the tape and found its mass then the balloons mass. finally we blew up the balloon and taped it to the triple beam balance and subtracted the empty balloons mass with the tapes mass from the filled balloon taped to the balance. we found out that air dose have mass but you got to find out the actual number
Why is a platform balance more accurate than a triple beam balance?
It is an opinion. If you like a platform balance, then it is more accurate to you. If you like a triple beam balance, then that is more accrate for you. It doesn't matter what other people say about it because you might think something else is more accurate. That is why this question is not answered.
What are some disadvantages of the beam balance?
Some disadvantages of the beam balance include being less precise than electronic balances, requiring manual adjustment for accurate readings, and being more susceptible to error from external factors such as air currents or vibrations.
How can one determine the air density?
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.
How do we know that something has mass like air even though we can not feel it?
We can feel it. We feel it as pressure. We can also weigh it. Take two balloons of the same size and inflate them the same amount so that they balance out on a balance scale. Now pop one of them. The balance will tip towards the intact balloon, showing that the air inside has some mass.
Uses of analytic balance?
Analytic balances are used in laboratories and research settings to accurately measure the mass of chemicals, samples, and reagents. They are essential for precise measurements for experiments, formulations, and quality control processes. Analytic balances are also used in industries such as pharmaceuticals, food and beverage, and environmental monitoring for precise weight measurements.
When a beam of ligh travel from glass into air the ray will do what?
the beam wil keep going
When weighing out NaOH pellets why does the mass as read on the optical scale of the balance continuously increase?
Because NaOH is a hygroscopic compound and continuously absorbs moisture from air and its mass becomes increased.
What is the name for a large body of air?
This forms a front it can be a cold or warm front
What is another word for air mass?
warm air mass and cold air mass
What is a large body of air with relatively uniform properties?
A large body of air with relatively uniform properties is called an air mass. Air masses are characterized by their temperature and moisture content, which is influenced by the region over which they form. When an air mass moves over a different area, it can bring its unique weather conditions to that region.
When air at the surface diverges airflow above must?
converge to balance the mass flow and vice versa. This divergence or convergence of air flow helps in maintaining atmospheric balance and circulation patterns on a global scale.
