You titrate a 25.00 mL solution of hydrochloric acid, HCl, with a 0.2015 M sodium hydroxide, NaOH, solution. The titration required 39.73 mL of the sodium hydroxide to reach the endpoint. What is the concentration (molarity) of the hydrochloric acid? HCI + NaOH →NaCl + H₂O Student work: 39.73 mL NaOH 25.00 mL HCI 1 L 1000 mL 1000 mL HCI 1 L HCI 0.0080055 mol HCI 0.02500 L HCI = 0.2015 mol NaOH 1 L NaOH 0.02500 mol 0.3202 M HCI 0.0080055 mol Read the feedback statements below and chose all that are applicable to the work shown. Choose one or more: The unit cancellation is not correct. The conversions to from mL to L do not need to be shown since they cancel out. The final answer has an incorrect number of s.f. (it should have 4 s.f.) The final answer has an incorrect number of s.f. (it should have 3 s.f.) Units do not cancel properly. The stoichiometry step to convert mol NaOH to mol HCI is not shown. All data collected, work shown, and final answer are recorded and shown correctly.

A food chemist determines the concentration of acetic acid in a sample of apple cider vinegar by acid- base titration. The density of the sample is 1.01 g/mL. The titrant is 1.002 M NaOH. The average volume of titrant required to titrate 25.00 mL aliquots of the vinegar is 20.78 mL. What is the concentration of acetic acid in the vinegar? Express your answer the way a food chemist probably would: as a percent by mass.
27 One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(11) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper (11) sulfate. Scrap iron is then added to this solution, and pure coppe metal precipitates out because of the following chemical reaction: Fe(s) + CuSO₂(aq) -Cu(s) + FeSO (aq) Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 350 ml copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass 122. mg. Calculate the original concentration of copper(11) sulfate in the sample. Be sure your answer has the correct number of significant digits. 02 0.9 15
