Question

(1) using the molar it yet of acetic acid in vinegar, calculate the mass percent of acetic acid in the original sample. assume the density of vinegar is 1.0g/mL. ( formula for acetic acid is C2H4O2) (2)look up the % acetic acid on a bottle of vinegar in your cabinet or at the Store? (b) what is is the percent error of your experimental determination from the actual on the bottle? (formula for percent error : accepted-experiemental/ accepted ×100. (3)if your standardized NaOH were used to titration 20.00mL of sulfuric acid (H2SO4), a diproticacid,what concentration of sulfuric acid would you determine if 24.66mL of the NaOH solution were required by the titration? first write the balanced equation for the reaction so as to use the correct stoichiometry in the calculation.
