water is a uniqu material in that the density of the solid is lower than the density of the liquid (which is why ice forms at the top of a pond and why ice floats in ours drinks). if the density for ice at 0 degree is 0.197g/mL and the density for water at 0 degree is 0.999g/mL what is the calcuated free space (as %) for each of these materials? why will need to estimate the volume of water as the sum of 2H atoms and 1 oxygen atoms with radii of 37 and 66 pm respectively. not that you will aslo have to assume a quantity of water to perform this exercise
