How do you calculate neon's relative atomic mass?

To calculate neon's relative Atomic Mass, you first need to consider the isotopes of neon and their respective abundances. Neon has three stable isotopes: Ne-20, Ne-21, and Ne-22. The relative atomic mass is calculated by multiplying the mass of each isotope by its natural abundance (expressed as a fraction), summing these values, and then dividing by the total abundance. The resulting value gives the weighted average mass of neon's isotopes, which is approximately 20.18 u.
