Yes. Not sure on the exact weights (as it depends on size of tank and pressure of the gas) but you can tell a definite weight difference between an empty and full tank because the compressed air does have a weight
A full cylinder is heavier than empty. The cylinder is filled by weight.
There will be a TW on the side of the cylinder this is the tare weight the weight of the cylinder empty. (TW 27) would be an 27 pound empty cylinder. A full cylinder will weigh 30 pounds more than the tare weight.
There is a fair amount of variation, but the standard small 16.4oz (1 lb) propane cylinder usually weighs just about a pound when empty (Tare weight, or the weight of the container itself). It is then usually charged with 16oz (by weight) of liquid propane for a total of around 32iz (2 lb).In SummaryTare Weight: 16oz (weight of the container/bottle)Net Weight: 16oz (weight of the liquid propane fuel)Gross Weight 32oz (weight of a full bottle)or in more practical terms, the closer your bottle is to weighing 1 lb, the closer you are to empty.
Normally it is done by weight. The empty cylinder weight is known and the weight with CO2 is taken and the CO2 weight is found.
Gas cylinders weigh about the same whether full or empty.
Presumably one is empty while the other one is full.
Your cylinder full of gas will weigh more, for it contains the mass of the gas. Some gases, when compressed, such as CO2, are in liquid form, and quite heavy.
It should weigh 45kg + the TARE weight of 36.6kg for the bottle = 81.6kg when full. The WC (water capacity) of the bottles are 109.8kg and LPG weighs 41% of water = 45kg. This is a good check to see if you are being ripped off by your gas supplier.
An empty gas container actually weighs less than a full container.
The mass of an empty 16 oz water bottle typically ranges from 10 to 20 grams, depending on the material and design of the bottle.
The weight of your stomach can vary depending on factors like age, body composition, and whether it's empty or full. On average, an empty adult human stomach weighs about 4 oz (113 grams).
An empty soda can will typically roll faster than a full soda can due to its lighter weight. The full can has more mass, leading to increased inertia which slows down its rolling speed compared to the empty can.
