Answer 2

Atomic mass is the sum of number of protons and of neutrons.

Aluminum contains thirteen protons and fourteen neutrons in it.

So, it's atomic mass is .

i.e.

Atomic Mass of Aluminum = Number of protons + Number of neutrons

=> 13 + 14

=> 27 u

$\textbf{27 u is the Atomic Mass of Aluminum.}$
