Vinegar is a solution of acetic acid (CH3COOH) in water. For quality control purposes, It can be titrated using sodium hydroxide to assure a specific % composition. If 25.00 mL of acetic acid is titrated with 9.08 mL of a standardized 2.293 M sodium hydroxide solution, what is the molarity of the vinegar?

0.832 M is the molarity of the vinegar solution whose volume is 25mL.

How we calculate the molarity?

Molarity of vinegar will be calculated by using the below formulas:

M₁V₁ = M₂V₂, where

M₁ = molarity of NaOH = 2.293 M

V₁ = volume of NaOH = 9.08mL = 0.00908L

M₂ = molarity of vinegar = to find?

V₂ = volume of vinegar = 25mL = 0.025L

On putting all these value in the above equation and we calculate for the value of M₂ as:

M₂ = (2.293 × 0.00908) / 0.025 = 0.832 M

Hence, 0.832 M is the molarity.
