What is the molality of a solution that has 4 mol of kci in 0.800 kg of water

In which direction will the following reaction go if the standard reduction potentials are 0.80 v for ag/ag+ and –0.44 v for fe/fe2+? ag+ + fe → ag + fe2+ a.)forward b.)the reaction cannot occur. c.) not enough information is given. d.) reverse

Match the mixture with the substance// i really need on this guys (it’s a pic btw)
