As I understand from your question, we should synthesize nickel sulfate first from nickel (II) oxide and sulfuric acid and second from nickel carbonate and sulfuric acid.
The chemical reactions will look like this:
NiO (s) + H₂SO₄ (aq) → NiSO₄ (aq) + H₂O (l)
NiCO₃ (aq)* + H₂SO₄ → NiSO₄ (aq) + H₂CO₃ (aq)
but carbonic acid will decompose to carbon dioxide and water
H₂CO₃ (aq) → CO₂ (g) + H₂O (l)
(*) NiCO₃ has a poor solubility in water, but enough to start the reaction.
1.3 x 10¹⁵ : 1.2 x 10⁹ = 1.083 x 10⁶
The amount of product obtained in a chemical reaction. The absolute yield can be given as the weight in grams or in moles.

<h2>
Answer:</h2>
Numer of moles of Li₂CO₃:
Chemical Reaction:
2 LiOH(s) + CO₂(g) → Li₂CO₃(s) + H₂O(l)
- 1 mole of Li₂CO₃ is formed from 2 moles of LiOH.
Therefore, applying unitary method:
- 0.53473 mole of Li₂CO₃ is formed from 2 × 0.53473 = 1.06946 moles of LiOH.
