Full or empty?
If empty, about 110 - 120 lb.
If full, about 1045 lb.
-- Just remember saltwater is less dense and therefore lighter than freshwater, so an aquarium filled with salt would weigh more. Also, you must take into consideration interior additives such as substrate, rocks and other solids, if you are trying to calculate the weight bearing of a floor or stand.
Just the weight of the water would be 720 pounds (8 pounds per gallon). The weight of the glass itself would probably be at least another 50, just from having had an aquarium half that size -- I know the tank empty weighed at least 25-30 pounds. So almost 800 pounds full. one gallon of water is 8 pounds, if you fill the aquarium with 90 gallons of water, 90 x 8 = 720 pounds plus the weight of gravel, filters, decor, fish, and the tank it self. could be as high as 800 pounds. It's a little more complicated, as a 90 gallon actually holds slightly less than 90 gallons (closer to 80), and much of the water will be displaced by stone and decorations. To answer your question specifically, a typical, empty 90 gallon glass aquarium weighs about 160 lbs, and about 1050 lbs filled with typical aquarium "stuff."
That depends on the type material you are referring to. Also, these are two different types of measurements. One is volume the other is weight or mass. Please edit your question to include more context or details.
About 200 lbs empty, and about 1400 lbs full.
1 gallon of water is 8.33 pounds so 500 gallons would be 4165pounds!
About 1043.75 lbs because each gallon weighs about 8.35 pounds. Then again, the glass could make it weigh more
Approximately 710 lbs when full of water. Probably around 60-80 lbs empty.
120 gallons
Well it depends. They sometimes weigh up to 500 pounds but its definitely between 300 and 500 pounds.

It depends on the size of tank you want. If your going to your local store the pricce ranges may vary. If you want a good tank to start get a 20 gallon full set up tank at your local pet stores. prices start at $80.
