How many carats is pure gold?A. 22 caratsB. 24 caratsC. 23 caratsD. 100 carats

To determine how many carats pure gold is, we need to understand the carat system:

Carat (K) is a unit of measurement used to express the purity of gold. The purest form of gold is considered to be 24 carats. This means that 24 out of 24 parts of the metal are gold, indicating 100% purity.
Explanation of the Options:
A. 22 carats: This indicates that the gold is 22 parts gold and 2 parts other metals (usually alloyed for strength), which means it is approximately 91.67% pure.
B. 24 carats: This represents pure gold (100% gold).
C. 23 carats: This indicates that the gold is 23 parts gold and 1 part other metals, making it about 95.83% pure.
D. 100 carats: This option is not a valid measure since carat purity is capped at 24 carats for gold.
Conclusion:
The correct answer is B. 24 carats, as this represents pure gold.
