WebHow many atoms are there in 1 mole of magnesium? 6.022x10^23 The correct answer to this problem is 6.022 x 10 23 A mole contains a certain amount of atoms no matter the compound or element. WebFor example, theatomic mass of an oxygen atom is 16.00 amu; that means the molar massof an oxygen atom is 16.00 g/mol. Further, if you have 16.00 grams of oxygen atoms, you know from the definition of a mole that your sample contains 6.022 x 10 oxygen atoms. The concept of molar mass can also be applied to compounds. scooby doo snacks meme
