# How do you find the atomic mass of sodium?

## How do you find the atomic mass of sodium?

Most sodium atoms have 11 protons and 12 neutrons, giving a total of ~23 amu, and dividing by 1 amu then gives 23 for the relative atomic mass.

## Why is the atomic mass of sodium 23?

Mass number = Total number of protons + Total number of neutrons Sodium atom has 11 protons and 12 neutrons in its nucleus. Thus, we get the atomic mass number 11 + 12 = 23. Na has the atomic mass number 23, so its atomic mass is 23 amu.
