Question

I am really strangling with the lab questions, I don’t getwhat the questions are about or how to solve them.

Please help me answer the first question.

Calculate the percentage of empty space in 1 mol of water at25C. Obtain the density from the experiment “somemeasurements of mass volume.” The volume of a molecule ofwater can be taken as the sum of the volumes of the two hydrogenatoms and the oxygen atoms. Use the single-bond covalent radii of37 pm from hydrogen and 66 pm from oxygen and V=4 pi r^3/3 tocalculate the volume of each atom.
