The density of copper is 8,96 g/cm3.
If they hang vertically, the weight is not moving, and is well-distributed, half of the weight will pull on each of the two chains.
Copper or aluminum AWG. As for gauge and such, it depends on how much amperage you have running through it, and the length of wire.
Where the weight of a fixture does not exceed 25 pounds it shall be permitted to be supported directly by the outlet box. Over 25 pounds it shall be supported independently of the outlet box.
Exactly 33,13035046 grams of copper.

The weight of a 2007 Cent is 2.5 grams. Of this, 0.8% is copper.
it depend on how much your doors been workin out :P
The value is determined by weight. Copper is currently about $3.75/pound, so weigh your copper and do the math.
How much what? Weight, value, use?
It depends on the quality of the cable (how much copper it has) and the gauge of the wire. The most common type of gauge is 18 AWG. Also, the weight depends on the type of packaging - wooden spools are the most common. An 1000' spool of 18 AWG coax on a wooden spool weighs 38.6 pounds.
Assuming you mean electrically, Copper is roughly 10 times less electrically-resistant than steel. That is probably the best measurement to gauge by for what you are asking.
4inch Schedule L Copper pipe weights 5.38 lbs/ft.
Due to the shape and weight of the two items.
