Answer:
c(Al³⁺) = 0.52 mol·L⁻¹; c(SO₄²⁻) = 0.84 mol·L⁻¹
Explanation:
One mole of aluminium sulfate produces 2 mol of aluminium ions and 3 mol of sulfate ions.
If we apply the same proportionality, 0.26 mol of Al₂(SO₄)₃ produces 0.52 mol of Al³⁺ions and 0.84 mol of SO₄²⁻ ions.
Al₂(SO₄)₃(aq) ⟶ 2Al³⁺(aq) + 3SO₄²⁻(aq)
I/mol·L⁻¹: 0.26 0 0
C/mol·L⁻¹: -0.26 +0.52 +0.84
E/mol·L⁻¹: 0 0.52 0.84

Answer:
The answer is
<h2>1.74 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of magnesium = 11.81 g
volume = 6.80 mL
The density of the metal is
We have the final answer as
<h3>1.74 g/mL</h3>
Hope this helps you
