What is the density of copper? Also what is the density
of zinc?

Copper is 8.92
g/cm3,
Zinc is 7.1
g/cm3.
When you go to search for density of materials, do not
forget to also search "specific gravity".

- If you don't quite understand what density
means, see the "Coach's
notes".
-
- Until 1982 pennies were made of copper;
Since 1983 they have been made of zinc with a thin copper
plating
-
-
- The chemical symbol for copper is Cu, and for
zinc is Zn.

- A
cooper makes wooden casks held
together with bands of steel, not copper.

Dude! That was so cool! Cause I had homework to find the
density of those two elements and they are right there!
Awesome! Who's getting an A? Me! Hurah! Keep putting stuff
like that up and I will pass Chem. for sure. Awesome!

Hai puzzled, i was given to carry out an experiment to
determine the density of coated cylindrical copper wire with
the following data diameter 0.22 mm, length 197 cm and mass
0.6g. The problem is that the answer should be almost the
standard density of copper.

Hi, Teddy. That sounds like a calculation, a homework question,
not an experiment. What part of the experiment did you actually do --
measure and weigh the copper? The answer is not off by a lot (less
than 10 percent). Show your work and we can point out your error.
