Why is the average atomic mass of neon considered to be 20.18 amu?
Why is the average atomic mass of neon considered to be 20.18 amu?
- It is an arbitrary value chosen for convenience in laboratory purposes (correct)
- Because all neon atoms in the sample have a mass of exactly 20.18 amu
- It is the sum of the individual atomic masses of the isotopes
- It is the mass of the most abundant isotope in the sample
