5. Iron has molar mass 55.8 g/mol. (a) Find the volume
of 1 mol of iron. (b) Use the value found in (a) to de-
termine the volume of one iron atom. (c) Calculate
the cube root of the atomic volume, to have an esti-
mate for the distance between atoms in the solid.
(d) Repeat the calculations for uranium, finding its
molar mass in the periodic table of the elements in
Appendix C.
