Compare and contrast the ease at which molecules are able to move relative to each other in the three states of matter
ANTONII [103]
The arrangement of molecules within the 3 phases of matter are shown in the picture. 

For the solid, the molecules are packed closely together. They don't have much space to move, so they just practically vibrate. For the liquid, the molecules are relatively farther from each other. The liquid molecules can flow freely but not as much as the gases. In the gases, the molecules are very far from each other. They are very sensitive to slight changes of pressure, volume and temperature.

LenKa [72]

Answers:  

                   Density = 0.8 g/mol.        

Given data:

                   v = 25 ml

                    m = 20 g

                    δ = ?

Solution:

               Formula for calculating density is given as,

                Density = Mass / Volume    

                 putting values  

                 Density = 20.0 g / 25 ml

                  Density = 0.8 g/mol.
