Question

Define define atomic mass calculate the atomic mass of sodium​

Answer 1

Answer:

It is the ratio of the average mass per atom of an element from a given sample to 1/12 the mass of a carbon-12 atom. The relative atomic mass in 1 mole of isotopes of sodium atoms is 23 g/mol.

Answer 2

Answer:

Atomic Mass can be best defined as 1/12 of the mass of a carbon-12 atom in its ground state. The mass of an atom can be accounted for by the sum of the mass of protons and neutrons which is almost equal to the atomic mass. This small change is due to the binding energy mass loss.

$i.e.,A=p+n$

$\left \ {{23} \atop {11}} \right. Na$ has atomic mass 23u.

In terms,of kgs.,= $23(1.6$ × $10^{-27}$) kg = 3.6x $10^{-26}$ kg.
