Question

An unknown metal sample with a mass of 14.8 g was obtained. The sample's density was measured and compared with known metal densities. Several metals are listed in the table. Metal Density (g/mL) - aluminum 2.70, iron 7.87, cobalt 8.90, copper 8.96, gold 19.3. What is the possible identity of this metal sample?

Options:
a) *Aluminum*
b) *Iron*
c) *Copper*
d) *Gold*

Answer 1

The identity of the metal sample cannot be determined without knowing its volume. If volume were known, the sample's density could be compared with the densities of known metals such as aluminum, iron, copper, and gold to identify it.

Step-by-step explanation:

To determine the possible identity of the metal sample with a mass of 14.8 grams, you would need to measure its volume and then calculate its density. The density of a substance is its mass divided by its volume (Density = Mass/Volume). Without the volume data, we cannot identify the metal. However, if you were able to determine the volume of the metal, you would then compare the calculated density with the provided metal densities to identify the metal. For example, if you found the density to be 2.70 g/mL, this would match the density of aluminum, making aluminum the likely identity.
