3.4 A 5.17 g sample of vinegar is titrated with 0.018 M NaOH. If the vinegar requires 42.3 mL of the NaOH solution for complete reaction, what is the mass percentage of acetic acid in the vinegar? (i.e. calculate the % of CH3COOH in the vinegar) The reaction is: NaOH(aq) + CH3COOH(aq) H2O(l) + NaCH3COO (aq) M,(CH3COOH) = 60.0

One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 250. mL sample of groundwater known to be contaminated with iron(II) chloride, which would react with silver nitrate solution like this: FeCl₂(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Fe(NO3)₂(aq) The chemist adds 16.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 2.0 mg of silver chloride. Calculate the concentration of iron(II) chloride contaminant in the original groundwater sample. Round your answer to 2 significant digits. mg 0 L x10 X Ś

Which of the following correctly expressed the balanced equation for the following word equation:

Fumaric acid is  quite common in the plant world and is added to many foods due to its acidity and fruity flavor.  It has a molar mass of 116.07 g/mol and a formula of C4H4O4. A solution of sodium hydroxide is used to determine the molarity of a fumaric acid acid solution before it is used to prepare some sour gummi worms.     C4H4O4(aq)   + 2NaOH(aq) --> Na2C4H2O4(aq) +2 H2O(l)   Calculate the Molarity of the fumaric acid if 32.08 mL of 0.09973 M NaOH was used to neutralized 75.00 mL of fumaric acid solution.  Assume the fumaric acid is acting as a strong electrolyte acid in this reaction.
