Answer:
3.88g/mL
Explanation:
Density could be understood as the mass of a compound when it occupies 1mL.
To find the mass in 1mL we need to determine the volume that the piece occupies:
Based on Archimedes' principle, the volume of water displaced is equal to volume of the aluminium piece, that is:
54.4mL - 41.8mL = 12.6mL
As the piece has as mass 48.9g, the density is:
48.9g / 12.6mL =
3.88g/mL
