<u>Step 1: Define</u>
[RxN - Balanced] 2Al (s) + 3H₂SO₄ (aq) → Al₂(SO₄)₃ (aq) + 3H₂ (g)
[Given] 0.418 mol Al₂(SO₄)₃
[Solve] <em>x</em> mol Al
<u>Step 2: Identify Conversions</u>
[RxN] 2 mol Al (s) → 1 mol Al₂(SO₄)₃ (aq)
<u>Step 3: Stoich</u>

- [DA] Multiply/Divide [Cancel out units]:
<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs.</em>
Since our final answer already has 3 sig figs, there is no need to round.
Answer:
The lowest energy conformer is shown in the figure.
Explanation:
In Cis form both the groups are in the same plane (towards the observer or away i.e on dash line or wedge line)
As shown in the diagram.
For cyclohexane terminology, both should be on up position or down position.
The two groups should be on equatorial position to have most stable conformation.
