you weigh its density and compare it with the density of gold, if both densities are same, then the crown is made of pure gold. if the density of the crown is lower than the density of gold, then the crown is made of materials that are cheaper or have a density that is less than gold, meaning that it is not made of pure gold.
Pure gold will have a serial number.
compare the samples density with that of pure gold
step 1. well you can put it in water and measure the variance step 2. you should theoretically calculate the amount of water that will be raised and you can know whether it is pure or not
Gold is an element; a molecule of gold (Au) is the smallest amount of gold that you can have that is not dividable into smaller amounts of gold. Whether or not a sample of gold is pure depends on the presence or absence of alloys or impurities blended with the gold.
run a test on the element type or try to bite it Biting is not very successul.
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.
Archimedes came across concept of density - that is MASS divided by VOLUME. For each substance this ratio is different but a CONSTANT for that substance. Thus the mass you are dealing with is irrelevant if the crown had the same ratio as the piece of pure gold then the crown was pure god, if it did not then the crown was not gold.

Yes Archimedes crown was pure gold. how they know this is that they weighed the dentisity of the crown.
Pure gold will have a serial number.
The Archimedes story relates that Archimedes had been trying to determine if the King's crown was pure gold, without having to melt it down (destroying it) to see. Archimedes sat down in the tub and noted that the water rose in the tub, and that he realized that the volume of water displaced was equal to the volume of Archimedes himself. This gave him an insight into how to determine the volume of the crown; by submerging the crown in water and measuring how far the water rose, this would give him the volume of the crown. He could then weigh the crown and calculate the density of the crown, and determine that the crown was not pure gold.
By studying the displacement of water caused by pure gold and silver of the same mass, he proved that the gold crown was not of pure gold as claimed by the jeweller.

One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.
