Answer 1

Answer:

$\huge\pink{\mid{\fbox{\tt{Answer}}\mid}}$

According to the average atomic mass: Since the overall atomic mass of neon in the average of the determined atomic masses of individual isotopes present in the sample of isotopic mixture Hence, no individual neon atom in the sample has a mass of 20.18amu. ... For CO In CO, there are one carbon and one oxygen atoms.

Answer 2

Answer:

Ans: Neon has three isotopes which have atomic masses and having relative abundance of 90.92% 0.26% and 8.82% respectively in the nature 20.18 amu is the relative atomic mass of Neon i.e the average atomic mass of all the three isotopes of neon. this is the that no individual Neon atom in the  sample  of the element has a  mass of 20.18 amu exactly.
