Density, mass of a unit volume of a material substance. Hope this helps!

Statement (E) is correct.

Explanation:

Both mass number and atomic mass are integer. Both are unit less.

Atomic mass is approximately equal to mass number of an atom with an unit of daltons or amu or u.

Mass number = number of protons + number of neutrons

So mass number of N = 7 +7 =14

So, atomic mass of n atom = 14 daltons

Hence statement (E) is correct.
