There is a ball with a mass of 1000 lbs.
It's turned into wire with a diameter of 3.12 x 10^-1
How long is the wire?

This is my crazy chemistry teacher's idea of a test...and I don't even think there's a solution. HELP ME

• chemistry -

We don't do tests but note you can't work the problem until you know what unit the 0.312 number is. Also, I think you need the density.

shoot, i wish i could remember the metal. she gave us the entire periodic information. how would i find the solution if I theoretically had the density?

• chemistry -

Density gives you a way to solve for volume.
