C. Vinegar Calculations 1. Write a balaneed chemienl equation for the reaction of acetic acid with sodium hydroxide. Don't forget to predict the products of this netatralization reaction (which is also a double displacement reaction in this case), c2H152(a5)+N1OH(aq)→Na4+C2H3O2+H3O( A) 2. Moles of NaOH used in titration mole NaOH Show calculation [−0.3∗81×1+ selufien 6.01322 3. Moles of CH3COOH neutralized by NaOH Show ealculation 4. Molarity of CH3COOH Show calculation * "enter thir ecetic acid molarity an page 136, question 2f. 5. Mass of CH3COOH gCH3COOH 6. Percent CHj COOH (vm×100%) in venegar m= mass of CH3COOH %CHCOOH v=5 mL of vinegar solation Show calcalation 7. Compare the experimental mass percent of acetic acid to the one stated on the manufecturer's label: Percentage relative difference =(%=fϵ%αpt⋅%mt)×100% Show calculation a. If your percentage relative difference is a positive number, what does that tell you? b. If your pereentage relative difference is a negative number, what does that tell you?
