Aluminium Sulphate (Al₂(SO₄)₃) consists of 2 aluminum atoms, 3 sulfur atoms, and 12 oxygen atoms per molecule. Each sulfate group (SO₄) has 4 oxygen atoms, and with 3 such groups, it totals 12 oxygen atoms in one mole. Key Points: 1. The molecular formula of Aluminium Sulphate is Al₂(SO₄)₃. 2. One mole of Al₂(SO₄)₃ contains: o 2 moles of Al atoms o 3 moles of S atoms o 12 moles of O atoms. 3. Commonly used as a coagulant in water treatment. 4. The calculation of moles is based on Avogadro’s number. 5. Total molar mass = 342 g/mol. Bee Facts: • 6 moles (a): Half the correct amount. • 9 moles (b): Incorrect calculation. • 12 moles (c): Correct number of oxygen atoms. • 8 moles (d): Underestimated number.
