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.
