Question

A student finds a piece of metal that she thinks is aluminum. She finds the volume to be 245 cm^3 and the mass to be 612 grams. Calculate the density of metals. Is the metal aluminum?

Answer 1

Answer:

Density = 2.5 g/cm³ , The metal is aluminium.

Explanation:

Density is defined as the ratio of the mass and the volume

Thus,

$Density=\frac {Mass}{Volume}$

Given that:

Mass  = 612 grams

Volume = 245 cm³

Thus, Density is:

$Density=\frac {612}{245}\ g/cm^3$

Density = 2.5 g/cm³

Metals are shiny with high density.

The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range.

The metal is aluminium.
