3 US gallons = 13,63827 L
Standardized air density: 1,225 g/L
Mass of air: 13,63827 x 1,225 = 16,70688075 g
The equivalent of of 16,707 g in pounds is 0,037.
It is strongly recommended to use only SI units !
It is roughly the same as the weight of a gallon of water, because the bouyancy force is equal to the weight of water displaced (the weight of the air being negligible). A UK gallon of water weighs almost exactly 10 pounds, while a US gallon weighs about 8.35 pounds.
That depends on what's in the gallon. -- 1 gallon of air weighs about 0.02 pound. -- 1 gallon of water weighs about 8.4 pounds. -- 1 gallon of gold weighs about 160 pounds. -- If the gallon is empty, then it has no weight at all ... zero pounds.
Approximately 5,000 gallons of air are needed to burn one gallon of gasoline in an internal combustion engine. This air combines with the fuel in a precise ratio for efficient combustion to power the engine.
Impossible to know without knowing the density of the fluid your measuring. 40 pounds of air = Lots of gallons. I'm guessing that you mean water ... so 40 pounds of fresh water at 68 degrees is about 4.8 gallons (8.33 pounds per gallon at standard conditions)
The pound is a unit of weight and the liter is a unit of volume. A liter of iron weighs many pounds while a liter of air weighs very little.

None. A pound is a measure of mass. A gallon is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. If you are not convinced, consider a gallon of air. How many pounds? Next consider a gallon of mercury. How many pounds?
5,775 cubic inches in 25 US gallons.
You can't answer this question as asked. Pounds are a weight/mass based unit of measurement, while gallons measure volume. You can say how many pounds a gallon of water weighs, for example, but a gallon of air (or flour or daisies or lead shot) would be radically different.
The best estimate would be about 13 pounds. Pounds is a unit of mass/weight. Gallons is a liquid measure. They do not convert cleanly. The density of the liquid being measured can make a big difference. If the liquid is water, there is 8 pounds to a gallon.
What year? The older air-cooled Beetles has at least three tank sizes, and the newer once may have had different sizes as well. Older air cooled models commonly used a 10.5 gallon tank, with larger ones available from the after market. Newer water cooled Golfs and New Beetles tend to have a 14 gallon fuel tank.
That depends what kind of substance you're filling it with. Air . . . very few pounds Water . . . around 450 pounds Stones or gold . . . a lot more than that
If you are referring to Air pumped from an "aerator' Then the answer is "none". A filter is needed not an air pump.
There can be no equivalence. A pound is a measure of mass. A gallon is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. If you are not convinced, consider a gallon of air. How many pounds? Next consider a gallon of water. How many pounds? The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
"Pound" is a unit of mass. "Gallon" is a unit of volume. These two units are used to describe completely different types of quantities, and they have different physical dimensions, so they don't convert to each other. If it were possible to convert masses to volumes, then you'd be able to figure out how many gallons you weigh. The mass of a gallon completely depends on what's in the gallon. -- If the gallon is full of air, it weighs about 0.0102 pound. -- If the gallon is full of water, it weighs about 8.4 pounds. -- If it's full of gold, then it weighs about 160 pounds. -- If the gallon is empty, then it weighs nothing ... zero pounds.
