The density of a pure gold ring would be slightly lower than a bar of pure gold because pure gold rings often contain other metals like copper or silver in their alloy. The addition of these metals decreases the overall density of the ring compared to pure gold.
The smaller pure gold ring will have a higher density than the larger one due to its smaller volume and higher mass. Density is a ratio of mass to volume, so as the volume decreases and the mass remains constant, the density increases.
Density is an intensive property of matter that is defined as the ratio of an object's mass to its volume. Mass is the amount of matter contained in an object and is commonly measured in units of grams (g). Volume is the amount of space taken up by a quantity of matter and is commonly expressed in cubic centimeters (cm3) or in milliliters (ml) (1cm3 = 1 ml). Pure gold has a density of 19.32 gm/cm^3 while 14k gold has a density between 12.9 and 14.6 gm/cm^3, depending upon the composition of the alloy. Legend has it that Archimedes discovered the principle of buoyancy by measuring the difference in the density of the king's new crown using this method. An experienced jeweler should be able to distinguish the pieces at little or no charge.
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.
Based on the periodic table, gold is heavier than silver.
To determine if the ring is pure gold, we can calculate its density using the formula Density = Mass/Volume. The calculated density of the ring is approximately 16.9 g/ml, which is lower than the density of pure gold (19.3 g/ml). Therefore, the ring is not made of pure gold, as its density does not match the density of pure gold.
You could compare the measured density of the bar of metal to the known density of pure gold (19.32 g/cm³). If the measured density matches the density of pure gold, there is a high likelihood that the bar is made of pure gold. If the measured density is significantly different, then the bar is likely not pure gold.

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.
The density of the shiny, gold-colored bar of metal is 12.19 grams over cubic centimeters. The density of a Gold(Au) is 19.3 grams over cubic centimeters. These means that the gold-colored bar of metal is not pure gold.
The smaller pure gold ring will have a higher density than the larger one due to its smaller volume and higher mass. Density is a ratio of mass to volume, so as the volume decreases and the mass remains constant, the density increases.
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.

To determine if the crown is pure gold, calculate its density using the formula density = mass/volume. Substituting the values given, the crown's density should be 1800 g / 110 cm^3 = 16.36 g/cm^3. Since the density of gold is 19.3 g/cm^3, the crown is not made of pure gold as its density is lower than that of 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.
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.
Density is specific for each substance. Also the measurement is generally simple.
