- One mole of Aluminium Sulphate Al2(SO4)3 contains 12 moles of oxygen atoms.
- To determine this, we analyze the chemical formula Al2(SO4)3.
- Each sulphate ion (SO42-) contains 4 oxygen atoms.
- In Al2(SO4)3, there are 3 sulphate ions.
- Thus, the total number of oxygen atoms is calculated as 3 (sulphate ions) × 4 (oxygen atoms per sulphate ion) = 12 oxygen atoms.
- This matches the provided answer of 12 moles of oxygen atoms in one mole of Aluminium Sulphate.
Additional Information
- Aluminium Sulphate is commonly used in water purification, paper manufacturing, and as a mordant in dyeing and printing textiles.
- It is also used in the food industry as a firming agent.
- The molecular weight of Aluminium Sulphate Al2(SO4)3 is approximately 342.15 g/mol.
- When dissolved in water, it dissociates into aluminium ions (Al3+) and sulphate ions (SO42-).
