A half inch thick tempered glass will weigh 6.75 lb/ft2. With that much thickness, it can support much of the weight of possibly a small child or small animal.
What size is it, width, length and thickness
many variables such as thickness that could effect the weight
Depends on what material the tank is made of, glass, plexi-glass, wood? What are the thickness of these materials?
How much a beaker weighs depends on the size of the beaker and the thickness of the glass. A small beaker might weigh a few ounces while a large beaker will weigh several times that.
That's depending of the design, outer measures, kind of glass, but merely on the thickness of (the wall and bottom of) the glass cylinder.
250 grams because water density is the same for ML to GRAMS. No if it was filled with water to 250 ml the water would weigh 250 grams. The beaker would weigh whatever, depending on the thickness of the glass.
Glass weighs 162 pounds per cubic foot. Tempering adds no weight. Glass is glass, except specialty glasses like high temperature glass, which weighs slightly more.
The weight of laminated glass varied greatly depending on the thickness of the pane, the thickness of the lamination, and the material the lamination is made from. Generally speaking, the lightest layer of lamination is a PVB interlayer with a 0.38 MM thickness, which adds about 0.40 KG to the weight. The heaviest lamination is a UV Liquid Interlayer with a 3.05 MM thickness, which adds about 3.22 kg to the weight.
the amount something weighs, depends on the volume of it you have and how dense it is. Though glass will have a fairly consistent density, in your question you only mention the thickness, if that glass were to cover an area of 50 square miles it would weigh more than if it only covered an area of 10 square millimetres.
