Aluminium Oxide(Al2O3) has 2 moles of aluminum and 3 moles of oxygen. The total is 5 moles.
One mole is 6.022 x 1023 atoms. Therefore, 5 moles = 30.110 x 1023 atoms
6*10^23 particles in 1 mole of everything you can count. (it's same like in "12 in one dozen")
One mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes.So you multiply 4.2 with 6.02 × 1023 to get 2.53 × 1024
16.2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum ------------------------------------------
Pieces of atoms? 6.01024 atoms of aluminum (1 mole Al/6.022 X 10^23) = 9.98047 X 10^-24 moles of aluminum ---------------------------------------------------
Aluminum is number 13 on the periodic table so each aluminum atom has 13 protons and 13 electrons.One mole of anything has is 6.022x1023 atoms (Avogadro's number)So 1 mole of aluminum has 13x6.022x1023 electrons

One mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes.So you multiply 4.2 with 6.02 × 1023 to get 2.53 × 1024
There are 13 protons in aluminum and 13 electrons. So, there are 13 atoms in aluminum. In oxygen, there are 8 protons and 8 electrons. thus there are 8 atoms. EDIT: This answer is absolutely and completely incorrect. (Dr.J.)
16.2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum ------------------------------------------
3.20 moles aluminum (6.022 X 1023/1 mole Al) = 1.93 X 1024 atoms of aluminum -------------------------------------------
16. 2 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 3.62 X 1023 atoms of aluminum -------------------------------------------

24 mols of aluminum must have reacted since aluminum oxide is Al2O3
The molar mass of aluminum oxide, Al2O3, is 101.96 g/mole.
Aluminum is number 13 on the periodic table so each aluminum atom has 13 protons and 13 electrons.One mole of anything has is 6.022x1023 atoms (Avogadro's number)So 1 mole of aluminum has 13x6.022x1023 electrons
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
