Result To complete this investigation, we have collected data and calculation of vinegar and acid. Three major questions were covered to gather the calculation of acetic acid in vinegar. Two trials of experiment gave data where we putted into equations of density, molarity and mass % to find the amount of acid in vinegar. Used NaOH and vinegar has a certain amount of volume that have been expressed in the following details and discussion. - As we found the density of vinegar first in the investigation, 0.52 M NaOH 10 mL vinegar solution - Three trials of investigation have different amount of NaOH used for vinegar. Therefore, we have take the average volume of milliliter to calculate the complete molarity for acetic acid First trial – 15.5 mL NaOH Second trial – 15.7 mL NaOH Third trial – 16.3 mL NaOH Average Volume of NaOH: 15.83 mL - To calculate the molarity, we need the moles of NaOH, so following calculation express

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
