Answer 2

The purity of gold is valued in karats. If it is 99.9 per cent gold, than it is said to be 24 karats. This gold is very soft. So ornaments are not made with pure gold. Ornaments that we wear are hard and long-lasting. To make gold hard, metals like copper, silver, cadium, and other metals are used. Depending on the amount of other metals that are mixed in the gold, the purity of gold get's reduced as 22 karats, 18 karats, 14 karats and less than that.

You already know that 24 karats of gold is 99.9 per cent pure. Similarly, 22 karats of gold is 91.6 per cent pure. It means that 8.4 per cent is other metals. If it is 18 karats of gold, than it just 75 per cent pure. Also, 14 karats of gold is 58.5 per cent, 12 karats of gold is 50 per cent and 10 karats of gold is 41.7 per cent pure.
