Question

If a galvanic cell is created with magnesium and potassium electrodes, what is E∘cell?

Report your answer with three decimal places.

	Half Reaction	E∘ (V)
	Mn2+(aq)+2e−⟶Mn(s)	−1.185
	Zn(OH)2(s)+2e−⟶Zn(s)+2OH−(aq)	−1.245
	Zn2+(aq)+2e−⟶Zn(s)	−0.7618
	Al3+(aq)+3e−⟶Al(s)	−1.662
	Mg2+(aq)+2e−⟶Mg(s)	−2.372
	Ba2+(aq)+2e−⟶Ba(s)	−2.912
	K+(aq)+e−⟶K(s)	−2.931
