R, universal gas constant is 8.314 J/ Kmole or 0.0821 L atm/K mol. in this case, apply 0.0821 for R since we are using liter and atm. If you calculate it right, it will give 40.3 L
If this question is asking about the intermolecular force, the ice have stronger intermolecular force that make the water particles to stay together.
bobpursley, I think the calculation is wrong. Al is oxidation, Pb is reduction. Ecell= E reduction (Pb) - E oxidation So the cell potential will be Ecell = -0.13 - (+1.68) = -1.81 V
