Explanation:
the answer and the working out is shown above, hope it helps.
Density is given by mass divided by the volume of a substance.
In this case the mass is 0.794 g and the volume is 0.82 cm ×1.45 cm ×1.25 cm = 1.48625 cm³.
Therefore, density = 0.794/ 1.48625
= 0.5342 g/cm³
Thus, the density of lithium metal is 0.5342 g/cm³

I think that's the answer they're going for.^
Answer:
multiply the first equation by 3 to cancel the electrons in both equations
then combine both equations
then minus both cell potentials which equals 0.78 V
I'm not sure though
