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?
3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industrial strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume of vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the'first minute of each reaction, and he records the data below. Volcano # 1 Time Volume of gas Volume of gas produced (mL) vs. Time (s) for Volcano #1 (s) produced (mL) 60 50 10 20 30 25 38 40 46 30 • Volume of gas produced (ml) 40 50 20 50 52 e 10 60 53 20 40 60 80 Time (s) Volcano # 2 Volume of gas produced (mL) vs. Time (s)…
You measure 15.0 mL of the H2C2O4 solution with a 100-mL graduated cylinder and add it to a 125-mL Erlenmeyer flask. Then you add two drops of the indicator, phenolphthalein, to the oxalic acid solution in the flask. You dispense the NaOH solution from the buret into the flask (while swirling the flask) until you reach the endpoint. At the endpoint, the solution in the flask turns light pink. You repeat the titration two additional times for a total of three trials. H2C2O4 (aq) + 2 NaOH (aq) --> Na2C2O4 (aq) + 2 H2O (l) (I) (II) (III) Volume of H2C2O4 used 15.00 mL 15.00 mL 15.00 mL how many Moles H2C2O4 are used in each trial?

Hello, Can you please answer these three short answer style questions for me? Thank you!
A stock solution whose concentration is 25.00 mg/mL was provided. A primary standard solution was then prepared by transferring 5.00 mL of the stock solution into a 50.00 mL volumetric flask. The primary standard solution was used to prepare three standard solutions of different concentrations by taking different volumes of aliquots into three 25.00 mL volumetric flasks: Standard Solution #1 #2 #3 Amount of Primary Solution (mL) 5.00 10.00 15.00 Three 25.00 mL volumetric flasks were then diluted to mark with water. Questions #1 What is the concentration of the primary standard solutions, expressed in units of mg/ml? #2 Re-write the concentration of the primary standard solutions obtained from Q#1 in units of μg/mL. #3 Determine the concentrations of three standard solutions in units of µg/mL. #4 What is a requirement for a "blank" solution used in calibration in spectrophotometry?
