Mass = Volume X Density. The volume is 20.0 cm X 6.0 cm X 1.0 cm = 120 cm3, so the mass is 120 cm3 X 19.3 g/cm3 = 2316 grams. A rounded-off answer of 2300 grams is more appropriate, given the way that the data is presented.
The density of gold is 19.3o g/cm3 at room temperature.
According to The equation D = M/V ( d = the density, M = the mass and v = The volume) then M = V*D
Thus M = 70 * 19.3
so according to your data, the mass is 1351g,
It is 482.5 grams.
The larger piece will probably have more mass than the smaller one. But if the wood is of the same type and "all things are equal" as regards moisture content, sap content, etc., the density of both pieces of wood will be the same. Density does not depend on the size of a sample. Density is mass per unit of volume. If a large gold nugget and a small gold nugget are compared, the larger nugget will have more mass, but both nuggets will have the same density.
how could you use density to show that a gold bracelet contains elements other that gold?
Its density can.
It would lower it.
The density of a given substance will not change as long as the purity remains the same. That is, if both the ring and the necklace are made of 14 karat gold, they will have the same density, but the overall mass of gold in each item is different.

15,000 g / 193 gcm3 = 77,7202 cm3
2300 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
The Density near r.t. Is: 19.30 g·cm−3 And the Liquid density at m.p. Is: 17.31 g·cm−3 Don't know the lbft3, perhaps somebody else can improve this answer.
Density is calculated by mass divided by volume. Mass is therefore calculated by density multiplied by volume. Make sure your units are compatible - 1L - 1000 cm3 So, gold statue's mass is 19.3 g/cm3 x 1700 cm3 = and sand's mass is 3.00 g/cm3 x 1700 cm3 =
its has higher density
19.3. Specific gravity is another way of saying density.
Exactly the same.
Exactly the same.
