You may be referring to the story of how Archimedes was able to determine if a crown had been made of pure gold (or less-than-pure gold) by measuring how much water the crown and an equal weight of pure gold displaced.
The event leading to Archimedes discovery is finding gold

Yes Archimedes crown was pure gold. how they know this is that they weighed the dentisity of the crown.
Archimedes wanted to know the density of gold to determine if the crown was partially silver rather than all gold.
Hiero II, the King of Syracuse, wanted Archimedes to determine if gold had been withheld from a crown by the goldsmith commissioned to make it. Without damaging the crown, Archimedes used water displacement to prove that the gold was not all there.

Archimedes was told by the king to find out if his crown was made of pure gold, calculating the density of the crown, Archimedes found it to be a mix of gold and silver.
don't hesitate to demur to the idea if you have any qualms
