What is the atomic mass of neon? give your answer to the nearest tenth.

Average Atomic mass = 20.2 amu

To calculate the average atomic mass of neon, we need to know it's naturally occurring isotopes, and the masses of these it's different isotopes.

The isotopes of neon are;

Thus;

Average Atomic mass = (90.92% × 19.99) + (0.3% × 20.99) + (8.85% × 21.99)

Average Atomic mass = 20.184 amu

To the nearest tenth gives 20.2 amu
