Gold and Silver at their purest have a very specific measurement of density. When measuring the density of a piece of metal if it is more or less than the pure level of density then it is not pure.
The formula for density is
D = M/V
where D = density, M = mass, and V = volume
If you had, say, 12 grams of gold, and it occupied 5 mL, the density would then be:
D = M/V
D = 12 g / 5 mL
D = 2.4 g/mL
The density of gold is about 19 g/cm3, or 19,000 kg/m3.
Pure gold has a specific density like all other substances.If an another substance was mixed with gold the density may fluctuate.Refer to Archimedes
Density= Mass/Volume 1800g/110 cm^3 = 16.36 g/cm^3 No, it is not pure gold.
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.
Pure gold has a density of 19.32 grams per cubic centimeter.A cubic foot contains 28,316.85 cubic centimeters.Thus, a cubic foot of pure gold has a mass of 547,081 grams,which on Earth weighs 1,206.1 lbs.!
The density of pure gold is 19.3 grams/cc. So 25 kg = 25,000 grams = 1295.3 cc
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.
If both objects are pure gold then the density is the same. Weight and mass are not factors in this particular question.
compare the samples density with that of pure gold
To test if something is pure gold, you will need to find out the density. The density of pure gold is 19.3 g/mL. To find the density, u will need to find out the mass and volume of the object then divide the mass by the volume ( m/V ). If your answer is not 19.3 then it is not pure gold.
I think it is the large gold ring
Sure, the density of pure gold would be greater than most other metallics, the density of gold is 19.32 g/mL, so anything less than that, and the bar would not be pure.
19.3 g/cm3
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.

Density can tell you how "pure" a substance is. Since each substance has a specific density in its "pure" state, having no other substances in its composition, by measuring it density you can tell how pure the mineral or substance is, 99.9% pure gold.
Pure gold has a specific density like all other substances.If an another substance was mixed with gold the density may fluctuate.Refer to Archimedes
Gold has a specific gravity of 19.29, silver has a specific gravity of 10.46. Gold is heavier.
