Answer:
0.0496 L
Explanation:
You are diluting the LiNO₃ solution, so you can use the dilution formula.
c₁V₁ = c₂V₂ Divide each side by c₁
V₁ = V₂ × c₂/c₁
c₁ = 4.13 mol·L⁻¹; V₁ =?
c₂ = 1.05 mol·L⁻¹; V₂ = 195 mL Calculate V₁
V₁ = 195 × 1.05/4.13
V₁ = 195 × 0.2542
V₁ = 49.6 mL Convert to litres
V₁ = 49.6 × 1/1000
V₁ = 0.0496 L
