A concentration cell contains a 1.0 M solution of lanthanum nitrate [La(NOs))] in one compartment and a 1.0 M solution of sodium fluoride saturated with LaF3 in the other. A metallic La strip is inserted into each compartment, and the circuit is closed. The measured potential is 0.32 V. What is the Kap for LaF,? Report your answer to two significant figures.
