Answer 1

✔️Atomic weight/mass:-

⭕️The atomic weight of an element is the mass of total number of protons and neutrons present in nucleus an atom.

⭕️It is determined with another element which is carbon.

⭕️It usually expressed in atomic mass units (amu).

⭕️One amu is defined as a mass equal one-twelfth the mass of one C-12 atom.

⭕All the atoms of an element have the same atomic mass.

Answer 2

$\textbf{Answer :}$



$\huge\textbf{Atomic weight :}$



Atomic weight is also known as Average atomic mass.


It is defined as average of the masses of a number of different atoms.


It's unit is $amu.$


Amu is defined as a mass equal to $\frac{1}{12}th$ the mass of C-12 atom.


Atomic mass unit = $\frac{Mass\:of\:C-12\:atom}{12}$
