A Ni(II) coordination compound with an octahedral arrangement of ligands has been synthesized containing only water and ammonia as ligands and chloride as counterions. From the following data, determine the exact formula of this compound. When 4.37x10^-4 moles of this complex is dissolved into 425.0 mL of water, you find that 17.49 mL of 0.1000 M HCl is needed to reach a titration endpoint. Make sure that your final formula contains the necessary counterions to make a neutral salt.
