I'm having problems with this question.

A piece of copper wire has a diameter of 0.389mm. If copper has a density of 8.92g/cc, how long (in meters) should you cut a piece of wire to obtain 0.0141 moles of copper?

I tried finding the volume of the cylinder and other things, but I'm completely lost!

can someone help me??

Try a simpler problem to start. What is the volume of a copper wire that has a diameter of 0.389mm and a length of 1m? What would be the mass of this wire?

Second, what is the mass of 0.0141mol of copper?
