... The gram mole is the grams of any chemical substance using the value atomic mass obtained from the periodic table. E.g. for carbon gram mole is 12.01 grams of carbon since its atomic mass is 12.01 amu in the periodic table. if you take atomic mass in grams the number of atoms is simply 6.022 x 10 23 ...

... You may recall that an element is a pure substance that cannot be broken down or separated into simpler substances. The reason an element cannot be broken down further is that it is already very simple: each element is made of only one kind of atom. Elements can be found in your pencils, your coins, ...
