The most and the least dense metals has to be given.

Concept introduction:

Density:

Density can be defined as property that links mass of an object to its volume.  It derived quantity and its unit is $\text{g}{\text{ml}}^{\text{-1}}$ for liquids and $\text{g}{\text{cm}}^{\text{-3}}$ for solid.  The density of material can be calculated with the help of formula,

  $\text{Density=}\frac{\text{Mass}\left(\text{g}\right)}{\text{Volume}\left(\text{ml}\text{or}{\text{cm}}^{\text{3}}\right)}$
