Question

The proportion of gold in the alloy

Carat is a measure of the purity of gold, indicating the proportion of gold present in an alloy compared to other metals.

Confusing Carat with Weight

Students often confuse carat, which measures the proportion of gold in an alloy, with the weight of the gold itself.

Clarify that carat refers to the purity of gold in an alloy, expressed as a fraction of 24 parts, rather than the weight of the gold.
