How do you calculate n Factor?

To calculate n-factor of a salt of such type we take one mole of the reactant and find the number of mole of the element whose oxidation state is changing. This is multiplied with the oxidation state of the element in the reactant which gives us the total oxidation state of the element in the reactant.

What is the oxidation number of Al2O3?

Is aluminium an oxide?

Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. … It is commonly called alumina and may also be called aloxide aloxite or alundum depending on particular forms or applications.

How many atoms of aluminum are in aluminum oxide?

2 aluminum atoms
Since the overall charge of a compound must always be equal to zero (neutral) we need 2 aluminum atoms and 3 oxygen atoms in order to balance out the charge and make the compound neutral. This means that the chemical formula for aluminum oxide is simply Al2 O3. That’s 2 aluminum atoms for every 3 oxygen atoms.Dec 9 2019

What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms molecules protons etc. To convert from moles to atoms multiply the molar amount by Avogadro’s number. To convert from atoms to moles divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

What is the value of 1 mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12 (12 g C = 1 mol C atoms = 6.022 × 1023 C atoms).
