WebJun 2, 2024 · To find the number of neutrons in an atom, you need to find the mass number for each element. The periodic table lists the atomic weight for each element, which can be used to find mass number, For hydrogen, for example, the atomic weight is 1.008. WebChemists defined the molar masses of elements such that a mole of atoms of a single element would be equal to its atomic mass, but in grams instead of u. So carbon's relative atomic mass is 12.01 u, but a mole of carbon atoms is 12.01 gram simply because we defined it to be so. Hope that helps. ( 4 votes) Krish 2 years ago Couldn't you just say
