[Fe3+]eq
Calculate [Fe3+ initial for each of the nine trials, i.e. the diluted concentrations of Fe(NO3)3 at the instantaneous moment after
mixing with KSCN, but before reacting. Using the values of [Felinitial for each of the nine trials and the values of [FeSCN²+]
calculate [Feeq for each of the nine trials.
