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?

The total cation content of natural water is often determined by exchanging the cations for hydrogen ions on a strong acid ion-exchange resin. A 25.00 mL sample of a natural water was diluted to 100.00 ML with distilled water, and 2.06 g of a cation - exchange resin was added. After stirring, the mixture was filtered and the solid remaining on the filter paper was washed with three 15.00 mL portions of water. The filtrate and washings required 16.30 mL of 0.0282 M NaOH to give a bromocresol green end point. a) Calculate the number of millimoles of cation present in exactly 1.00 L of sample. b ) Report the results in terms of milligrams of CaCO3 per liter. Only typed solution.
2. Hemoglobin is a protein that carries oxygen in the blood. It absorbs light strongly at a wavelength of 400 nm, which gives blood its red color. A solution of hemoglobin is diluted to 10 times its original volume (1.0 mL hemoglobin + 9.0 mL water). The diluted solution has an absorbance value of 0.354. a) Determine the absorbance value of the original solution. Explain how you arrived at your answer. b) It would be simpler to measure the absorbance of the original solution directly. Explain why it is better to dilute the solution before measuring the absorbance for this sample. 3. Why is it important not to touch the sides of the cuvette with your fingers?
A chemist needs to create a series of standard Cu2+(aq)Cu2+(aq) solutions for an absorbance experiment. For the first standard, he uses a pipet to transfer 20.0020.00 mL of a 2.952.95 M Cu2+(aq)Cu2+(aq) stock solution to a 500.0500.0 mL volumetric flask, and he adds enough water to dilute to the mark. He then uses a second pipet to transfer 20.0020.00 mL of the second solution to a 50.0050.00 mL volumetric flask, and he adds enough water to dilute to the mark. Calculate the concentration of the Cu2+(aq)Cu2+(aq) solution in the 50.0050.00 mL volumetric flask.

A student begins a titration experiment by filling her first buret with unknown acid to the 1.12 mL level. She fills her second buret with base, NaOH, and records an initial volume of 0.08 mL. At the end of the titration experiment and after the pale pink endpoint is obtained, she records her final volume of acid in the buret as 18.85 mL, and the final volume of base in the second buret as 28.74 mL. In the first blank below, please indicate the volume of acid used in her experiment. In the second blank, please indicate the volume of base used. For both answers, please report your answer WITH the correct number of significant figures or decimal places, and WITHOUT a unit. Question 1 options: ___________ answer #1 ___________answer #2
A biochemist carefully measures the molarity of calcium carbonate in 62. mL of photobacterium cell growth medium to be 67. µM. Unfortunately, a careless graduate student forgets to cover the container of growth medium and a substantial amount of the solvent evaporates. The volume of the cell growth medium falls to 6.0 mL. Calculate the new molarity of calcium carbonate in the photobacterium cell growth medium. Be sure your answer has the correct number of significant digits.

The concentration of hydrogen peroxide in a solution is determined by titrating it with a 0.1217 M permanganate solution. The balanced net ionic equation for the reaction is: 2MnO4 (aq) + 5H₂O₂ (aq) + 6H3O+ (aq) → 2Mn²+ (aq) +50₂ (1) + 14H₂O(1) In one experiment, 19.09 mL of the 0.1217 M permanganate solution is required to react completely with 40.00 mL of the hydrogen peroxide solution.
