how much does a gallon of water way, my mom is freaking out thinking the stand won't hold the tank. She won't get off my back until I prove her wrong (for the thousandth time).

One gallon of water weighs 8.3 pounds, and each cubic foot of water weighs 62.4 pounds
thats freshwater, salt is a little more.

I think a US Gallon of water weighs 7 pounds. Not including, gravel, deocrations, stand, filter and anything else you put in.

"A pint's a pound the world around."
Eight pints to the gallon.
Nominal "gallon" measurement of commercially-built tanks are usually higher than actual gallons they contain.
Rocks and gravel are heavier than water.

The easiest rule of thumb when dealing with tank weight is that the average fish tank, gravel, stand, tank, and water, weighs about 10 to 12 lbs/gallon. Just take the size of your tank and add a zero to get a nice round number... This only applies to the "bare bones" type stands, heavier wooden or wrought iron stands would of course add more to the weight...
Just for an example, I've got a rather nice, heavy stand on my tank, and a really deep gravel bed, and my 55 gallon weighs about 650 lbs., stand and everything (had it weighed dry, and added the water weight for approx. 45 gallons of water). I wanted to make sure my floors would hold it at my new home.
1 US gallon of pure H2O weighs 8.35 lb (or 3.79 kg)
Geez guys, you *REALLY* need to convert from Imperial to Metric.
How many more space probes you need to lose to realise this? :)
Even the Brits use Metric now.
1 Liter of water weighs 1kg.
What can be simpler :)
