The measured Eocell=+2.222 V. Using EoMg2+/Mg= -2.372 V, calculate Eo Sn2+/Sn in volts

Given the line notation:       Pt(s) | X+(aq), X2+(aq) || Y3+(aq) | Y(s)                         where: X2+ + e-  X+              Eo = 0.93 V Y3+ + 3 e-  Y             Eo = -2.48 V Pt4+ + 4 e-  Pt           Eo = 1.20 V                       Calculate the EMF.

A weather ballon is inflated on a beach from 0.00800m^3 to 2.90m^3. How much pV-work in kJ was performed by the balloon on the surroundings? (101.3 J=1 L atm; 1 m^3=10^3L)
