a piece of nickel wire has a diameter of 0.568. if the nickel has a density of 8.90g/cc, how long( in meters) should you cut a piece of wire to obtain 0.0234 moles of nickel?

A diameter of 0.568 WHAT?

Convert diameter to cm if it isn't that now, then take half of that to obtain radius.

Convert 0.234 moles Ni to grams.

moles = grams/molar mass. Solve for grams= xx g

Convert xxg to volume using

mass = volume x density.

Then pi*radius^2*length(in cm) = volume. You know volume, pi, radius, solve for length in cm and convert to m.
