A 0.3360 g sample of potassium hydrogen phthalate is dissolved in 100.0 mL of water. If 29.47 mL of sodium hydroxide solution are required to reach the equivalence point, what is the molarity of the sodium hydroxide solution? Be sure to report your answer with the correct units and number of significant figures. Your Answer: Answer units
Aa.23.
An aqueous sodium nitrate (NANO3) solution must be created for an experiment. If 50.00 mL of a 0.150 M solution is needed, what amount of sodium nitrate (in grams) must be weighed out? Only input numbers. Your answers must be expressed to the thousandths place. Any values less than one must have a zero in front of the decimal (e.g. 0.01 not .01).
A student prepares a dilute solution of sodium hydroxide, NaOH (aq), starting with 6 M sodium hydroxide. She then titrates a 1.372 g sample of KHP with the dilute sodium hydroxide solution, NaOH (aq), to a phenolphthalein end point. A.) If the titration required 21.84 mL of sodium hydroxide, NaOH (aq), calculate the molar concentration of the sodium hydroxide solution, NaOH (aq). (Remember that KHP is potassium hydrogen phthalate, KHC8H4O4, NOT potassium hydrogen phosphorus!) B.) The student uses the same sodium hydroxide to titrate 10.00 mL of vinegar to a phenolphthalein end point. If the titration required 27.48 mL of sodium hydroxide, NaOH (aq), calculate the molar concentration of acetic acid, HC2H3O2 (aq), in the vinegar. C.) Calculate the mass percent of acetic acid, HC2H3O2 (aq), in the vinegar using the molar concentration for acetic acid, HC2H3O2 (aq), determined in part b and assuming the density of the solution is 1.01 g/mL.
Answer in scientific notation (as needed) and use appropriate sig figs. A drink mix sample is prepared by mixing a packet of beverage powder in a gallon (3.78 L) of water. A sample for analysis is prepared by diluting 10.00 mL of this solution in a 50.0 mL volumetric flask. A student calculates that the concentration of dye in the analyzed beverage mix solution is (2.20x10^-5) mol/L. What is the mass (in grams) of food dye in the beverage mix packet?
Q22: Phosphate buffer solution is purchased as a(n) 2x stock solution. The solution is more concentrated than the working stock. If tasked with making 128 mL of a 1x solution of PBS, how many mL of the stock solution would be needed? Report your answer in standard decimal notation rounded to one decimal place.
A student prepares a 0.28 mM aqueous solution of acetic acid (CH,CO,H). Calculate the fraction of acetic acid that is in the dissociated form in his solution. Express your answer as a percentage.

When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization. In this lab, you will be provided with a stock solution of food dye. This is the solution from which you will prepare all of your standard solutions. The concentration of the stock solution will be approximately (7.200x10^-5) mol/L. How many milliliters of this stock solution is needed to prepare 50.0 mL of a (3.00x10^-5) mol/L solution?

A chemistry student weighs out 0.166 g of sulfurous acid (H,SO,), a diprotic acid, into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1300 M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Round your answer to 3 significant digits.
A lab prepared a solution of sulfuric acid with a volume of 5.0x10-4 m3. The solution is further concentrated to the half of the original volume, which is used to neutralize a potassium hydroxide solution. The potassium hydroxide solution has a volume of 30 mL, contains 30 g water, and has a density of 1.0141 g/cm3. What is the molarity of sulfuric acid in the concentrated solution? (The final answer keeps 4 digits after decimal. Please do NOT use scientific notation.)
