Answer:
Molarity of HCl= 1.3 M
Explanation:
Given data:
Volume of HCl = 25.0 mL
Molarity of HCl = ?
Volume of NaOH = 15 mL
Molarity of NaOH = 2.0 M
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Molarity of HCl
V₁ = Volume of HCl
M₂ = Molarity of NaOH
V₂ = Volume of NaOH
Now we will put the values.
M₁ × 25 mL = 2.0 M × 15 mL
M₁ × 25 mL = 30 M.mL
M₁ = 30 M.mL / 25 mL
M₁ = 1.3 M
