Discussion Forum
Since the size of the atoms is too tiny and we cannot compare their masses with conventional units, what unit do we use instead?
What is one relative atomic mass equal to?
Using this in q2, what mass of hydrogen is equal to carbon-12 atom?
What are the relative masses and charges of the sub-atomic particles in an atom?
