EXPERIMENT 1: Calculate the concentration of starch you prepared in cuvettes 1, 2, and 3. For the first cuvette: multiply the concentration of the diluted starch solution in the Erlenmeyer flask from the workbench that you calculated in a previous question by the volume of the diluted starch solution you added to the first cuvette. Divide that number by 2.5 mL, which is the total volume in the cuvette. For example, if the concentration of the starch solution in the flask was 0.5 mg/mL and you added 1.5 mL to the cuvette, you added 0.75 mg of starch. Divide that 0.75 mg of starch by 2.5 mL to get 0.3 mg/mL of starch. For the second cuvette, divide the first cuvette concentration by 2 because you used half the amount in cuvette 2 as you did in cuvette 1. For the third cuvette, divide the first cuvette concentration by 4 because you used one-quarter the amount in cuvette 3 as you did in cuvette 1. Record your results for use in future questions. Select one: a. 0.04 mg/mL, 0.02 mg/mL, and 0.01 mg/mL b. 4 mg/mL, 2 mg/mL, and 1 mg/mL c. 1.6 mg/mL, 0.8 mg/mL, and 0.4 mg/mL d. 16 mg/mL, 8 mg/mL, and 4 mg/mL
