Crytalline...?

Question

If let say 1 mole of water occupies 18cm^3 and one molecule is average at the center of a small cube, what will be the length of the sides of the small cube? What will be the diameter of the molecule compare with that length?

Answer 1

Avogadro's number = 6.0221415 × 1023 This is how many molecules in a mole.
the volume of each molecule is then 18/A cm^3.
The side of cube is the cube root of the volume.
The diameter = the side
