Question

how to find atomic mass of iron​

Answer 1

Answer:

Just find a periodic table, or go to p-table.com. Find iron (“Fe”) and you'll see a number above it (26) and a number below it (usually) like 55.85. This is both the average mass of an iron atom (in amu) and the molar mass (in g/mol). So see, no calculations needed!

Answer 2

add number of protons and number of neutrons of iron nucleus and you will get its mass number or atomic mass that is 56
