Can someone please show me step-by-step, if possible, how to calculate C3, C1, C2, and K?
The chemist I. N. Vino Veritas acquired the data shown below in a Job's method determination of the equilibrium constant for the formation of the iron (III) thiocyanate ion: Fe^+3_(aq) + SCN^-1_(ag) = FeSCN^+2_(aq). The equilibrium constant is given by K= [FeSCN^+2]/[Fe^+3][SCN^-1] = c_3/c_1c_2. Veritas's data at 480 nm: Absorbance, A = 0.303 for a solution with mu = 1/3. The stock solutions were at the same concentration of c_0 = 0.00100 M. The path length was b = 1.00 cm. Use this data to find the concentrations to four significant digits to avoid round off error, but report the equilibrium constant to three:
