How Much Do Bars of Gold Weigh?

• Gold is highly valued for its beauty, malleability, and purity.
• Gold, a metal, is prized for its malleability, resistance to corrosion, and rarity.
• It is highly coveted for jewelry, as it does not tarnish or corrode, and for industrial applications, such as use in computers.
• Gold is widely used as a hedge against inflation.

Gold's purity makes it extremely valuable for both industrial and ornamental purposes. A troy ounce of this precious metal can be bought and sold for significantly more than an ounce of silver or platinum, which makes it desirable.

Density of Gold

Gold, in its purest form, is composed of 99.99% pure metal. About 10% of that is pure "gold atoms" (Au) and 90% is pure "gold ions" (Au3+). The rest are "gold compounds."
Gold has a density of 19.3 grams per cubic centimeter (g/cm3). That's almost the same as water and about half as dense as lead. Gold is denser than many other metals, so price per ounce isn't always a good indication of how much gold a product contains.
