The specific gravity of 22 carat gold is around 17.7 to 17.8. This means that a 22 carat gold coin will be approximately 17.7 to 17.8 times denser than an equal volume of water.
Gold has the highest specific gravity of the three materials listed. Wood has the lowest specific gravity, while quartz falls in between wood and gold in terms of specific gravity.
To convert 24 carat gold to 23 carat gold, you will need to add an alloy to reduce the purity of the gold. Typically, silver is used as the alloy to decrease the carat value. The amount of silver added will depend on the desired carat value and the weight of the gold being converted.
The difference between 10 carat gold and 18 carat gold is the purity of the gold content. 10 carat gold is made up of 41.7% gold, while 18 carat gold contains 75% gold. This means that 18 carat gold is more valuable and pure compared to 10 carat gold, which has a lower gold content.
24 Karat gold is pure gold .The term Karat refers to the percentage of gold versus any other metal . Since gold is too soft , it is combined with other metals . 24 Karat - 100 % 18 Karat - 75 %
It is not possible to convert 18 carat gold into 22 carat gold as the carat purity indicates the percentage of gold in the alloy. To achieve 22 carat purity, you would need to add more pure gold to the alloy.

The weight of 18-carat gold depends on the specific piece being measured, as it can vary based on its size and design. However, 18-carat gold is composed of 75% pure gold and 25% other metals. To find the weight of a specific item made of 18-carat gold, you would need to measure it directly or refer to its specifications.
Gold has the highest specific gravity of the three materials listed. Wood has the lowest specific gravity, while quartz falls in between wood and gold in terms of specific gravity.
The Royal Mint does not issue 9 carat gold coins.
