\nThe chemical formula for Aluminium hydroxide is Al(OH)\u2083. This formula indicates that one molecule of Aluminium hydroxide contains one atom of Aluminium (Al) and three hydroxide groups (OH). Each hydroxide group (OH) consists of one Oxygen atom (O) and one Hydrogen atom (H). Therefore, one molecule of Al(OH)\u2083 contains a total of 3 hydrogen atoms (one in each of the three OH groups).
\n<\/section>\n
\nA mole is a unit of amount of substance, equal to Avogadro’s number (approximately 6.022 \u00d7 10\u00b2\u00b3) of elementary entities (atoms, molecules, ions, etc.). If one molecule contains a certain number of atoms of a particular element, then one mole of molecules will contain the same number of moles of those atoms.
\n<\/section>\n
\nIn one mole of Al(OH)\u2083 molecules, there are Avogadro’s number of Al(OH)\u2083 molecules. Since each molecule has 3 hydrogen atoms, there are 3 \u00d7 (Avogadro’s number) of hydrogen atoms. This quantity of hydrogen atoms represents 3 moles of hydrogen atoms.
