1. The equation for a Beer's Law plot is y = 2012.5x + 0.003. If the recorded absorbance for an equilibrium mixture is 0.362, what is the concentration of FeCNS2+ (aq)?
2. You are stuck using an older spectrophotometer that only reports % transmittance. Can you substitute %T in the Beer's Law for absorbance? (YES or NO or SOMETIMES)
3. What are the units for Absorbance?
