Suppose that pure gold was to be made into a very long, thin wire for high-end stereo systems. (Gold is often used because it does not oxidize so it makes very good electrical contacts). If the gold wire was to have a radius of 0.01 cm, how long of a wire could you make from 111 g. of gold?

    Convert 111 g to the volume of gold by dividing by the density. Then use
    Wire length = Volume/(pi*r^2)
