Using the procedure you leamed in the Hardness of Water laboratory, determine the average molarity of the acetic acid solution 30,4 ml 45,2m 14.8m1 Given that the Equilibrium constant (at room temperature) for acetic acid is 1.8x30 (remember equilibrium constants are unitiess). Given the equation below, determine the equilibrium expression and using the concentration you determined for Acetic Acid in question #1 determine the concentration of Hydronium (,0) at equilibrium CH₂CH₂CH. Calculate a mass percentage of acetic acid in vinegarusing the moles of acetic acid (not molarity) you calculated in question #1, the molar mass of acetic acid and assuming vinegar has a density of 1.00 g/ml Commercial vinegar is 5.00% and approximately pH 2.3. Using your determined values, calculate a percent error for your mass percentages and pH.
