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.
