Hey! For a lot of elements, the no of protons = no of neutrons
So for simple elements like Oxygen, Nitrogen, etc you can simply double the atomic no.
Eg. Atomic number of Oxygen is 8 and its mass is 16
You only need to learn the mass for specific elements like Chlorine (35.5)

your answer is good but i am asking for elements like einstinium or mercury or lead etc. whose atomic mass is not about too double

Oh, okay! I am not too sure about those but just a tip, if you are preparing for an exam, they usually specify the atomic mass in the question itself so you don't need to learn
