A soft drink contains an unknown mass of citric acid, C3H5O(COOH)3. It requires 6.42 mL of 9.580 × 10−2-M NaOH to neutralize the citric acid in 10.0 mL of the soft drink. C3H5O(COOH)3(aq) + 3 NaOH(aq) → Na3C3H5O(COO)3(aq) + 3 H2O(ℓ) Determine which step in these calculations for the mass of citric acid in 1 mL soft drink is incorrect? Why? n (NaOH) = (6.42 mL)(1L/1000 mL)(9.580 × 10−2 mol/L) n (citric acid) = (6.15 × 10−4 mol NaOH) × (3 mol citric acid/1 mol NaOH) m (citric acid in sample) = (1.85 × 10−3 mol citric acid) × (192.12 g/mol citric acid) m (citric acid in 1 mL soft drink) = (0.354 g citric acid)/(10 mL soft drink) Determine the correct result.
A sample of freshly precipitated and filtered silver chloride weighs 459.0 mg. If 1.00% of the silver chloride becomes photodecomposed and converted to solid silver metal, what will the precipitate weigh? Write on the space provided for your answer only the number with the correct number of significant figures.

A chemistry student weighs out 0.0909g of hypochlorous acid HClO into a 250.mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1400M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the equivalence point. Be sure your answer has the correct number of significant digits.
Five standard solutions of HBr are prepared by serial dilution in which, at each stage, 10.00 mL are diluted to 120.00 mL. Given that the concentration of the most dilute solution is 3.52 × 10−6 M, determine the concentration of the original HBr stock solution.
please see image attached: A chemistry student weighs out 0.146 g of chloroacetic acid into a 250. mL volumetric flask and dilutes to the mark with distilled water.

An aqueous solution of sodium hydroxide, NaOH , is made by dissolving 15.6 grams of sodium hydroxide in sufficient water in a 500. mL volumetric flask, and then adding enough water to fill the flask to the mark. What is the weight/volume percentage of sodium hydroxide in the solution? Weight/volume percentage = %
Five standard solutions of HBr are prepared by serial dilution in which, at each stage, 10.00 mL are diluted to 130.00 mL. Given that the concentration of the most dilute solution is 3.42 ×10−6 M, determine the concentration of the original HBr stock solution.
A geochemist measures the concentration of salt dissolved in Lake Parsons and finds a concentration of 25.·gL−1 . The geochemist also measures the concentration of salt in several nearby non-isolated lakes, and finds an average concentration of 4.2·gL−1 . Assuming the salt concentration in Lake Parsons before it became isolated was equal to the average salt concentration in nearby non-isolated lakes, calculate the percentage of Lake Parsons which has evaporated since it became isolated. Round each of your answers to 2 significant digits.

Following the procedure, a student recorded the initial volume of sodium hydroxide in his buret as 0.15 mL. He then titrated a 15.00 mL sample of 0.1027 M hydrochloric acid until a persistent pale pink appeared. He recorded the final volume of sodium hydroxide in his buret as 23.93 mL. What is the concentration (M) of his sodium hydroxide solution? Report you answer with four places after the decimal.
