What is the Difference Between Relative Atomic Mass and Atomic Mass? Relative atomic mass is calculated using the masses and the percentage abundance of ...

Atomic mass is the sum of all the protons, neutrons, and electrons in a single atom or molecule. However, the mass of an electron is so small, it is considered negligible and not included in the calculation. Though technically incorrect,...

The unit used to describe the mass of an atom is AMU. Post IUPAC's recommendation in 1993, nowadays, amu is increasingly replaced with another unit, making amu obsolete.

In this article, we will discuss atomic mass & molecular mass in chemistry class 11. So let's get started... Atomic mass and molecular mass: chemistry class 11, NCERT What is atomic mass? The atomic mass or the mass of an atom is actually very-very small because atoms are extremely small. Nowadays we have sophisticated techniques,
