A54-gram sample of an unknown material has a volume equal to 20 cm3
. based on its density,

D = m/V
d = 54/20
d = 2,7 g/cm³

Could the sample be aluminum?YES, this sample is aluminium - the density of chemical elements can be found in the periodic table.

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab.
