Question

A sample of aluminum has a mass of 5.4 g what is its volume

Answer 1

I'd say Incomplete Question.

If its an Objective Question... I'd approach like this.

The density of Aluminum usually lies around 2.6~ 2.7g/cm³

From

Density =Mass/Volume

Volume = mass/Density = 5.4g/2.7gcm-³

= 2cm³.
