If Archimedes had only been able to find a piece of pure gold with a mass one - half that of the crown how could he have determined whether the crown was 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.
What has a higher density a small pure gold ring or a large pure gold ring?
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.
Gold colored ring has a mass of 18.9 grams and a volume of 1.12 ml. Is the ring pure gold (The density of gold is 19.3 gml.) Explain.?
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.
What is heavier gold or silver?
Gold has a specific gravity of 19.29, silver has a specific gravity of 10.46. Gold is heavier.
If you bought a gold ring and found it had a volume of 0.3 mL and that it weighed 5.7 grams is it pure gold?
To determine if the ring is pure gold, we can calculate its density using the formula density = mass/volume. The density of the ring is 5.7 grams / 0.3 mL = 19 grams/mL. Since pure gold has a density of approximately 19.32 grams/mL, the ring's density is close but slightly lower, suggesting it may not be pure gold and could contain other metals.
What is the mass in grams of pure gold cube that has a volume of 4.40 cm cubed?
To find the mass of a pure gold cube with a volume of 4.40 cm³, you can use the density of gold, which is approximately 19.32 g/cm³. By multiplying the volume by the density, the calculation is: 4.40 cm³ × 19.32 g/cm³ = 84.73 grams. Therefore, the mass of the gold cube is approximately 84.73 grams.
A king's crown has a volume of 110 cm cubed and a mass of 1800 g The density of gold is 19.3 g cubed Is the crown pure 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.
A shiny gold-colored bar of metal weighing 57.3g has a volume 4.7 cm3 Is the bar of metal 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.
What is the karat for pure gold?
Pure gold is 24 karats. This means it is 99.9% pure gold.
Is the volume of gold 20g greater than the volume of lead 10g?
We need to calculate the volume of a metal from the density to be sure. Density of pure gold = 19.3  g·cm-3Density of pure lead = 11.34  g·cm-3The volume of 20 g of gold = mass/density = 20 [g] / 19.3  g·cm-3 = 1.036 cm3 The volume of 10 g of lead = mass/density = 10 [g] / 11.34  g·cm-3 = 0.882 cm3 Hence, the volume of 20 g of gold is slightly greater than that of 10 g of lead. =========================
14 karat gold jewelry or fashion gold jewelry how can a housewife tell the difference?
A quick way would be to see how much water it would displace. That would give you its volume. Weigh the ring and divide that by the volume of water the ring displaces (because the ring displaces a volume of water equal to its own volume). Use or convert to grams and milliliters, which are equal to cubic centimeters (or cc's). By dividing the ring's weight (its mass) by its volume, and then getting the answer in grams per one cc, you can compare your results with the density of pure gold. The density of pure gold is about 19.8 grams per cc, and with that information, you can make an educated guess as to whether or not the ring is pure gold.
If pure gold has a density of 19.32 gcm3. How large would of gold be if it had a mass of 318.97 g?
The volume of the gold can be calculated using the formula: Volume = Mass / Density. Substituting the given values, Volume = 318.97 g / 19.32 g/cm^3 = 16.52 cm^3. So, the gold would have a volume of 16.52 cm^3.
