this is analytical chemistry please show solution thanks

Supply the missing information in the table. (Given in Blue). Answers in scientific notation should be in this sample format >>> 1.0 x 10-14

I need help with one of my pre-lab questions which I want to understand. Its question number 2, the one that highlighted. I don't want to make it over-complicated, I want something that I can understand.

I need the answer as soon as possible

Please show solution and use laws for error calculation.

A student performed titration to find the concentration of acetic acid. Titrant was sodium hydroxide. He went beyond the indicator color change by adding too much titrant. How will his experimental error affect the calculated value for the concentration of unknown acetic acid? calculated value actual value. calculated value < actual value calculated value = actual value. more information is necessary this is not a source of error

Eight hydrochloric acid solutions were titrated and the concentration was determined to be as listed below. Calculate the average concentration in mM and report your answer with three places after the decimal. [hydrochloric acid] (M) 0.01079 0.00718 0.00749 0.01159 0.01367 0.01278 0.00926 0.01304

Find the Final volume of buret (mL) and the Concentration of NaOH (M )

why are pH measurements significant upon studying chemistry? How will it benefit us?

In carrying out the first standardization in this experiment, a student used 0.5169 g of potassium hydrogen phthalate (KHP) and 24.17 mL of a NaOH solution are needed to reach the equivalence point. What is the concentration (in mol/L) of the student's NaOH solution? Include only the numerical answer (no units). be careful with significant digit

You have a solution of a standardized titrant of 0.01254 M and a sample that approximately has a molarity of 0.48 M. What dilution do you have to do to spend approximately 15 mL of titrant if you have 25 mL and 10 mL pipettes to take the diluted sample and value it ? Solution: With the 10 mL pipette, the sample should only be previously diluted 1:25, with the 25 mL one 1:64. Therefore, 10 mL of the sample can be taken and made up to 250 mL.

In the experiment, the amount of acetic acid in vinegar was determined by titrating with 0.1 M NaOH solution. In the analysis, three trials were performed to obtain more precise result. The table shows the initial and final burette readings for three titrations:     Initial Burette Reading (mL) Final Burette Reading (mL) Trial 1 2.9 10.6 Trial 2 10.6 18.1 Trial 3 18.1 25.7   According to the given data, calculate molarity of acetic acid in the commercial vinegar. Please be sure that your answer includes followings; a) moles of NaOH for each trial                                              b) average mole of NaOH                                                         c) average mole of acetic acid in 50 mL solution                     d) average mole of acetic acid in 250 mL solution                   e) molarity of acetic acid in vinegar.

3. 8.0 mL of HCI was added into a 10.0 mL graduated cylinder and weighed on a centigram balance. Looking at the photo to the right, record the mass to the nearest 0.01 Sost ha 12.71 gram in your data table (line 4)

5. If the label on the bottle lists the citric acid content as 1 g per serving with a serving size of 240 mL determine the percent error in the titration results. Express result with 2 significant figures.

The following volumes of 0.000300 M SCN- are diluted to 15.00 mL. Determine the concentration of SCN- in each sample after dilution. These values will be used during the experiment.  Sample 0.000300 M SCN- (mL) [SCN-] (M) 1  1.50   2 3.50   3 7.00   4 10.00

You do it three times be- tween an acid and sodium hydroxide solution. Here is some data: Average volume of sodium hydroxide solution delivered: 9.10 mL Concentration of sodium hydroxide standard solution: 0.1010 M Average mass of acid solution: 9.555 g The average volume of sodium hydroxide solution is the average of three titra- tions. In other words, you did the experiment three times and took an average. The same goes for the average mass of the acid. You ran the experiment three times and the average mass of the acid solution is given for those three titra- tions. The sodium hydroxide solution was standardized and the concentration is given. Show your step-by-step calculations for this experiment to find the mass per- cent of acid in the solution.…

Two 24.91 ml samples of apple juice were analyzed using 0.1000 M NAOH solution by the method in this experiment. The corrected mean titration volume of the NaOH solution was 15.87 mL. Calculate the malic acid concentration of the apple juice in units of g/L. Assume that only malic acid is present in the juice. State the value to 2 places after the decimal point, Do not enter units.
