A student titrated a 30 mL sample of vinegar aiming to find the molarity of acetic acid in it. The student used X mL of 0,25 Molar NaOH solution. Find the molarity of acetic acid in the vinegar. (X=Last two digits of your student ID. Example: student ID=509181274, 74 mL NaOH is used. If it ends with double zero, take it as 17 mL). Write the equation of reaction between acetic acid and sodium hydroxide.
