First you need to define what you mean by gallon; an Imperial gallon is 4.546 litres, a US gallon is 3.785 litres, and a US dry gallon is 4.405 litres.
At 20oC water weighs 0.9982kg/l, so an Imperial gallon being 4.546 litres weighs 4.546 X 0.9982 = 4.538kg.
The density of seawater averages about 1.025 grams per milliliter. With conversion factors of about 3,785 milliliters per gallon and 453.6 grams per pound, this means that a gallon of seawater comes to roughly 3,879 grams or just under 8.5 pounds in weight.
US Gallons: 334 lb. Imperial Gallons: 400 lb.
The mass of 1 gallon of water is approximately 3785.41 grams. This may be expressed as 3.78541 kilograms as well.
8.35 pounds to the US gallon => 334 pounds
10 pounds per Imperial gallon => 400 lbs.
About 334 pounds for 40 US gallons.
About 8.35 pounds per US gallon.
Water weighs about 8.345404 lbs per/gal......
The actual weight of the aquarium itself would depend on the materials used. The rocks in the bottom would add some weight as well. If you want to know how much the water weighs. The mass (weight) of fresh water is about 8.35 pounds per gallon, so that is 459.25 pounds for the water.
Number 2 or red diesel weighs 8.33 pounds per gallon. It is slightly heavier than water which weighs 8.13 pounds per gallon.
liquid mercury's weight is 30 times the weight of water. Water's weight is 8 lbs per gallon, 30 times the weight of water will be 240lbs for a gallon of liquid mercury.
