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.

Yes, the density of pure gold is a well-known physical property, which is approximately 19.3 grams per cubic centimeter. This density value is often used to confirm the purity of gold objects through measurement.
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
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.
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.
No, the density of gold remains constant regardless of its size. Density is a physical property of a substance that is determined by its mass and volume, so as long as the material remains the same, the density will also remain constant.
To calculate the volume of the gold bar, we first need the density of gold. The density of gold is approximately 19,320 kg/m^3. Using this value, we can calculate the volume of the gold bar by dividing the mass of the bar (25 kg) by the density of gold. This would give us the volume of the gold bar in cubic meters.
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.!
