The absorbance of a cationic iron(II) sample solution was measured in a spectrophotometer, but the instrument returned an error because the absorbance was too high. The sample was then diluted by using a pipette to take 100.0 µL of the sample and injecting it into a cuvette already containing 2.00 mL of water (total volume is 2.00 mL + 100.0 µL). The absorbance value of the diluted solution corresponded to a concentration of 8.89x10-6 M. What was the concentration of the original solution?

A chemist needs to create a series of standard Cu²+ (aq) solutions for an absorbance experiment. For the first standard, he uses a pipet to transfer 10.00 mL of a 2.07 M Cu²+ (aq) stock solution to a 500.0 mL volumetric flask, and he adds enough water to dilute to the mark. He then uses a second pipet to transfer 5.00 mL of the second solution to a 100.0 mL volumetric flask, and he adds enough water to dilute to the mark. Calculate the concentration of the Cu²+ (aq) solution in the 100.0 mL volumetric flask. concentration: M

Phenobarbital was introduced in 1912 for the treatment of epilepsy. It is an anti-convulsant and sedative-hypnotic drug and used to control seizures. The measurement of phenobarbital is by fluorescence method. A 5.00 mL aliquots of an unknown containing phenobarbital were delivered to 50.00 mL volumetric flasks. The following volumes of a standard solution of phenobarbital, 2.00ug/mL, were then introduced to the volumetric flasks before diluting to volume with the corresponding signals on a fluorometer equipment. Find the concentration of phenobarbital in the original unknown sample.

25.0 mL aliquots of a 0.106 mol/L Sn2+ 2*(aq) solution was used to standardize an acidified potassium dichromate solution. The average volume of titrant used in the standardization was 27.63 mL. The acidified potassium dichromate solution was then used to titrate 15.0 mL aliquots of a solution containing Cr2*(aq). An average volume of titrant used in this second series of titrations was 43.53 mL. What is the molar concentration of the Cr2+(aq) solution? Answer to three decimal places.
A prospector wants to know how much gold is in the ore that he has been mining. A sample weighing 11.2456 grams is dissolved in Aqua Regia (a mixture of HCl and HNO3). That sample is then transferred to a 200.00 mL volumetric flask and diluted to the mark with water. This is called solution 1. A volumetric pipet is used to transfer 10.00 mL of solution 1 to a second 500.00 mL volumetric flask. The second flask is filled to the mark resulting in solution 2. 5.00 mL of solution 2 is analyzed and found to contain 13.45 ppm Au. Answer each of the questions below. 1. What is the concentration of Au in solution 1. The units should be ppm 2. How many micrograms of Au are in the 5.00 mL sample that was measured? 3. How many micrograms of gold were in the 500.00 mL flask containing solution 2. 4. How many grams Au were in the flask containing solution 1 5. What is the %Au in the original sample?
The exact concentration of a Na2S2O3 standard solution was determined by using KIO3 stock solution. 0.2189 g of KIO3 (potassium iodate Mr = 214.00 g/mol) were diluted to 200 cm3. 25 cm3 samples were titrated (after addition of acid and KI, proper amount in excess).

A 36.0 mL sample of aqueous sulfuric acid was titrated with 0.250 M KOH(aq) until the acid-base indicator signaled that the solution was neutralized. The mixture was then carefully evaporated to dryness, the residue was dried in a drying oven. The residue was then weighed and a value of 861 mg was obtained for its mass. Calculate a value for the volume of the potassium hydroxide solution that was used in the titration from this data. Answer with correct units and significant figures.
