Will give brainliest to correct answer one way to identify a substance is to compare the density of the substance with the density of a known substance. suppose a cube of a gold-colored metal with a volume of 58 cm3 has a mass of 979 g. the density of pure gold is known to be 19.3 g/cm3. based on this information, could the metal be pure gold? a.no. the density is more than pure gold. b.no. the density is less than pure gold. c.yes. the density equals that of pure gold.

In the video, the water level was 15 milliliters before adding the chain, and 20 milliliters after adding the chain. when i weighed the chain, its mass was 68.7 grams.i believe the chain is solid metal (not gold plated), but is probably a blend of gold and other metals. i looked up that gold has a density of 19.3 g/ml, while the other metals like silver and copper usually blended with gold have a combined density of about 9.7 g/ml.determine what percentage of the chain is gold, by mass, to at least 1 decimal place?

Gold has a density of 19.32 g/cm3. if a square pyramid has a base edge length of 5 cm, height of 6 cm, and a mass of 942 g, is the pyramid in fact solid gold? if it is not, what reasons could explain why it is not? recall that density can be calculated with the formula density=mass /volume
