A bottle in the lab is labeled [CoCl2·6H2O] = 0.71 M in 9.217 M HCl. If you determine [CoCl4^2-] to be 0.361 M at a particular temperature using absorbance measurements, what must be the value of [Co(H2O)6]^2+ in the solution at that temperature? Express your response to three digits after the decimal.
