6*10^23 particles in 1 mole of everything you can count.
(it's same like in "12 in one dozen")
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
This is a mole stoichiometry problem. Start with the balanced equation for the synthesis of aluminum oxide: 4Al + 3O2 --> 2Al2O3. The ratio of aluminum to aluminum oxide in this equation is 4:2, or 2:1, so 5.23 moles Al means half that number for Al2O3, so about 2.62 moles of aluminum oxide will be produced.
50 g Al2O3 is equivalent to 0,49 moles.
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
2.026 mole ironIII oxide
24 mols of aluminum must have reacted since aluminum oxide is Al2O3
The molar mass of aluminum oxide, Al2O3, is 101.96 g/mole.
