Answer:
Molarity of HCl = 0.12 M
Explanation:
Given data:
Volume of HCl = 13.0 mL
Volume of NaOH = 36.11 mL
Molarity of NaOH = 0.045 M
Molarity of HCl = ?
Solution:
Formula:
M₁V₁ = M₂V₂
M₁= Molarity of HCl
V₁ = Volume of HCl
M₂ = Molarity of NaOH
V₂ = Volume of NaOH
M₁ × 13.0 mL = 0.045 M × 36.11 mL
M₁ = 1.62 M.mL / 13.0 mL
M₁ =0.12 M
