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".

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.
