Question

Determine the emf of each of the following cells. Refer to thetable.
(a) Cr(s) |Cr3+(aq, 0.42mol·L-1) || Pb2+(aq,6.9*10-3mol·L-1) | Pb(s)

(b) Pt(s) | H2(g, 2.0 bar) |H+ (pH = 4.4 || Cl-(aq, 0.86mol·L-1)) |Hg2Cl2(s) | Hg(l)

(c) C(gr) | Sn4+(aq, 0.073 mol·L-1),Sn2+(aq, 0.073mol·L-1) || Fe3+ (aq,0.37 mol·L-1),Fe2+(aq, 0.37mol·L-1) || Pt(s)


(d) Ag(s) | AgI(s) | I -(aq,0.012 mol·L-1) || Cl-(aq, 0.96mol·L-1) | AgCl(s) |Ag(s) I know thatEo=ERo-ERobut what do I do with the molarities that are given in the problem.Again, any help will be greatly appreciated and I will ratewell.
