Help please with my pre lab. I know to find the average I will add the percentages and divided by 2 but how do I find the absorbance?
For the equilibrium: the initial concentration of Fe(NO3)3 is 0.00200 M and initial concentration for KSCN is 0.00200 M

Using the information provided, these questions needed to be
answered. My group and I are struggling to find the average Kf
using the absorbance of the solution. Please help we are
struggling.
