1.	Al2(so4)3 contain 3.2 gm of sulphur. then weight of al in sample is??
Answer» 3 x 32 GRAMS of Sulphur is present in 1 mole of Al₂(SO₄)₃ So, 3.2 grams of Sulphur is present in ¹/₃₀ moles of Al₂(SO₄)₃ We, know each mole of Al₂(SO₄)₃ contains 2 moles of Al So ¹/₃₀ moles of Al₂(SO₄)₃ contains ¹/₁₅ moles of Al Mass of ¹/₁₅ moles of Al = 27 x ¹/₁₅ = 1.8 grams Therefore, mass of Al in the sample is 1.8 grams. Hope it helps!!

Answer»

3 x 32 GRAMS of Sulphur is present in 1 mole of Al₂(SO₄)₃

So, 3.2 grams of Sulphur is present in ¹/₃₀ moles of Al₂(SO₄)₃

We, know each mole of Al₂(SO₄)₃ contains 2 moles of Al

So ¹/₃₀ moles of Al₂(SO₄)₃ contains ¹/₁₅ moles of Al

Mass of ¹/₁₅ moles of Al = 27 x ¹/₁₅ = 1.8 grams

Therefore, mass of Al in the sample is 1.8 grams.

Hope it helps!!
