Answer:

you work out the moles by finding the grand formula mass them you divide the actual mass by the grand formula mass: 25/160 (my grand formula mass is probably slightly different from yours) which I got 0.15625 then I times it by 32(O2) and I got 5. but my periodic table is different. it's whole numbers. ;-)

Explanation:

4.44

Write the full Nernst Equation (i.e. not just at 298K) and define each term:

alex41 [277]

Answer :

The Nernst equation :

$E_{cell}=E^o_{cell}-\frac{2.303RT}{nF}\log \frac{[Anode]}{[Cathode]}$

where,

$E^0$ = standard cell potential

n = number of electrons in oxidation-reduction reaction

F = Faraday constant = 96500 C

R= gas constant = 8.314 J/Kmol

T = temperature

[Anode] = anodic ion concentration

[Cathode] = cathodic ion concentration
