How could you use density to determined whether a bar of metal is pure gold?
You could compare the measured density of the bar of metal to the known density of pure gold (19.32 g/cm³). If the measured density matches the density of pure gold, there is a high likelihood that the bar is made of pure gold. If the measured density is significantly different, then the bar is likely not pure gold.
