1. a. How many grams of CuSO4•5H2O are needed to prepare 100.0 mL of a 0.15 M CuSO4 solution?
b. In order to make a solution that is 0.030 M in CuSO4, what volume of the above solution should be diluted to 5.00 mL with water?
2. A 0.10 M solution of compound "B" is measured in a 1.00 cm path length cuvette at a wavelength of 500 nm. The percentage of light transmitted through the cell is 38%.
a. What is the absorbance of this sample (A) at 500 nm?
b. Assuming Beer's Law holds, what is the value of e for compound B at 500 nm?
c. A sample of compound B having an unknown concentration is measured to have an absorbance of 0.90 in a 1.00 cm path length cell at 500 nm. What is the concentration of B in this sample, assuming Beer's Law holds?
