What is the concentration of SCN" in a solution prepared by adding 5.0 mL of 0.0020M SCN" to a test tube and diluting to a total volume of 10.0 mL? Once you get this answer correct, enter it on the Lab 13 Data Sheet in the first table as [SCN]; in test tube for Test Tube 4. At 590 nm, crystal violet (a biological stain) has a molar absorptivity (ɛ) of 8.7×104 M'cm-1. Using Beer's Law, calculate the concentration of crystal violet in a solution with a measured absorbance (A) of 1.254. The path length (b) is 1.00 cm.
