The calculation formula of gold and water is: fineness of gold = weight of gold in air/weight of gold in water/19.32. The density of gold is19.32g/cm3. Weigh the gold to be measured to obtain the mass m of the gold, put the gold into a container filled with water, and measure the volume v of the overflow water, so as to obtain the density of the gold to be measured according to the formula: density P= (mass m) divided by (volume v). Gold is the elemental form of gold (Au), which is a soft, golden yellow and corrosion-resistant precious metal. Gold is a rarer, more precious and more valuable metal.
