Amount of silver nitrate taken = 269.μmol
Volume of the solution = 300. mL
Concentration of a solution is generally expressed in terms of molarity. Molarity is defined as the moles of a substance present per liter of the solution.
We want the concentration in millimoles/L.
Converting μmol to millimol solute:
μ
= 0.269 millimol
Volume from mL to L:
Therefore concentration of the chemist's solution =

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.
