How can to tell if gold if fake?
Put it in warm water, after a while, if its colour disappears it's fake, if not it's real. This is because gold does not react with water. but golden coating reacts with water. You could always use the same method that Archimedes used. He measured the displacement of the water when the crown was submerged as well as the weight to determine the density of the crown. He then compared the crown's density to a pure gold reference density. If the densities matched, then they were both of the same purity of gold. Note: Gold's density is 19.3 g/cm**3 edit: Density can be measured (as mentioned above). Melting temperature is also a good indicator of purity (if you're willing to part with the gold's form).
How can i tell if my ring is silver or white gold?
It should be stamped with a "hallmark." A hallmark for silver should be "925." This indicates 92.5% pure sterling silver. Another hallmark for silver could be "STERLING". A U.S. hallmark for gold would be 10K or 14K or 18K indicating the gold content. Pure 100% gold would be 24K; 10K is 41.67% gold; 14K is 58.33% gold; 18K is 75% gold.
If a crown weighing 5 lb 10 oz desplaces 195 mL water when place in a bathtub is the crown made of pure gold d19.3gcm3?
There is no way to tell if a crown weighing 5 lb. 10 oz. is made of real gold given that it displaces 195 mL of water when placed in a bathtub because we do not know the volume of the crown. If the crown has hollow sections it will displace more water than a crown that is pounded flat.

What does the number of carats tell you about a pieceof gold?
The carats tell how pure the gold is. Pure gold is 24 carat. The fraction of 24 carats that the carat count is would be the fraction of gold in a piece of jewelry. For example, 18 karat gold is 75% gold and 12 karat is 50% gold.

What are two reasons why density is a useful property identifying substances?
Density can tell you how "pure" a substance is. Since each substance has a specific density in its "pure" state, having no other substances in its composition, by measuring it density you can tell how pure the mineral or substance is, 99.9% pure gold.
What does 9258 mean on a ring?
When you buy gold jewelry, look for the karat quality mark. The karat mark should tell you how much pure gold is in the piece. Pure gold – 24 karat (24K) gold – is soft, so it's often mixed with other metals to increase its hardness and durability.
What are the numbers on Italian gold?
The numbers tell you how pure the gold is: 10K, 14K, or 24K. I can't remember the exact equivalencies now but I am sure that they are on the internet.
