If the initial volume reading for the second titration was 0.76 mL and the final volume reading was 11.73 mL, what volume of iodine solution was used in your second titration (in mL)? Include the unit and two decimal places in your answer.

An analytical chemist weighs out 0.138 g of an unknown monoprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. He then titrates this solution with 0.0600M NaOH solution. When the titration reaches the equivalence point, the chemist finds he has added 25.5 mL of NaOH solution. Calculate the molar mass of the unknown acid. Round your answer to 3 significant digits. 0 mol X S 629 OL A

What volume, in mL, of 0.1126 M sodium hydroxide (NaOH) is required to titrate 15.00 mL of 0.1012 M acetic acid (HC₂H₂O₂)? Be sure your answer has the correct number of significant digits. mL X

An analytical chemist weighs out 0.181 g of an unknown diprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with 0.1700 M NaOH solution. When the titration reaches the equivalence point, the chemist finds she has added 15.9 mL of NaOH solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits. ol. g mol Ar

A student measured the mass of an empty micropicnometer to be 2.000g. A student places 0.500mL of citric acid solution into a micropicnometer. The student reweighed the micropicnometer and found the mass of the citric acid solution and micropicnometer to be 2.525g.    A student titrates 0.101mL of citric acid solution using the standardized 0.1M solution (use the exact concentration calculated from the previous titration problem). The sample required 0.819mL of NaOH solution to reach the end point.   Given the following chemical equation.   NaOH   +  H3C6H5O7 →  Na+ +   H2O  +   C6H5O73-   Given the above information. Calculate the mass of citric acid in the 0.101mL citric acid solution.    Given the above information. Calculate the total mass of the 0.101mL citric acid solution.

If your first titration yielded a concentration of 0.4 mg/mL and your second titration yielded a concentration of 0.54 mg/mL, what was the average concentration for your two titrations (in mg/mL)? Include the unit and two decimal places in your answer.

If the initial volume reading for the first titration was 0.32 mL and the final volume reading was 8.64 mL, what volume of iodine solution was used in your first titration (in mL)?

Acetic Acid Titration with NaOH. 50.00 ml of an acetic acid solution is titrated with 0.1000 M NaOH. 23.90 mL NaOH is required to reach the endpoint of the titration. What is the molarity of the acetic acid solution? (Do NOT include units)
