Question

Write the atomic weight of iron

Answer 1

Hey, 55.845 is the atomic weight of iron

Answer 2

Explanation:

Atomic weight or atomic mass means the sum of total number of protons and neutrons present in an atom.

For example, atomic weight of iron is 56.

That is there are 26 protons and 30 neutrons present in an atom of iron.

Hence, atomic weight = total no. of protons + total no. of neutrons

                                     = 26 + 30

                                     = 56

Thus, we can conclude that atomic weight of iron is 56.
