1. The printed label on a bottle of commercial vinegar states that the acetic acid concentration is 5%. (a) If the manufacturer had reported two significant figures int he concentration, what would the percentage range be so that all values would round to 5%? (b) Calculate the concentration in molarity of the upper and lower values from (a). The molecular weight of acetic acid is 60.05 g/mol. How many digits can you report in your answers? (c) What assumption did you make to calculate the concentrations in part (b)? (d) What is the percentage difference in the concentrations you calculated in part (b)? Explain what value you chose for the denominator in this calculation? 2. Acetic acid is a monoprotic weak acid with a pK_a of 4.74. (a) What is the pH of 10 mL of a 5.0% solution? (b) What is the pH of the solution if you now add 30 ml of water to solution (a)? 3. How will the equivalence point volume differ if you titrate the two solutions in question 2? Explain your answer. I know this is a lengthy question, but if you could provide detailed step-by-step solutions and explanations, I'd really appreciate it
