Sir, u please tell me how to calculate the atomic mass of an element, if the atomic number is known?

Expert Answer:

To determine mass you need to know number of neutrons as well. Atomic mass is mass of protons and neutrons. Atomic number only tells us about the number of protons, so we have to find out number of neutrons as well.
