MENT K Acid-Base Titration: How Much Acid Is In Vinegar? B. Calculate the molarity of acetic acid in the diluted vinegar sample using the calculated moles of HC2H;O2 in the 15.00 mL diluted vinegar sample. Remember to find molarity the volume must be in liters. (Show work below) M of HC,H,O, in diluted vinegar sample 4. Give the molarity of acetic acid in the vinegar before it was diluted. The original vinegar from the store is 10 times more concentrated than the diluted vinegar sample used in the titration. O-02754M of HC,H,O, in undiluted or original vinegar CALCULATIONS FOR MASS PERCENT OF ACETIC ACID IN VINEGAR 5. Convert the moles of acetic acid (HC,H,0,) in the diluted vinegar sample (previously calculated in question 2) to grams of HC,H,O,. Show your work. (You will need to use the molar mass of acetic acid for this calculation.) g of HC,H;O2 5. Using the equation below, calculate the mass percent of acetic acid in the diluted vinegar sample. The density of the vinegar is 1.00 g/mL so you can assume that the mass of vinegar in grams is essentially equal to the volume of vinegar in mL. Show your work below. mass of acetic acid x 100 Percent by mass = mass of vinegar sample % by mass of HC,H;O, in diluted vinegar sample 7. Give the percent by mass of acetic acid in the vinegar before it was diluted. The original vinegar from the store is 10 times more concentrated than the diluted vinegar sample used in the titration. % by mass of HC,H;O, in undiluted or original vinegar
