The task is to determine the percentage of trithiocyanato cobalt(II) complexes in a solution with specified concentrations and stability constants. By applying the stability constants to calculate the concentrations of various cobalt complexes, we can find the desired percentage of the trithiocyanato complex relative to all cobalt species present."}
