Does it make sense to say that a textbook is about 99.9 percent empty space?
A) No. A textbook is a solid and thus is quite dense. Therefore it is not 99.9 percent empty space.
B) No. Only gases are considered to be 99.9 percent empty space. Liquids and solids are not.
C) Yes. A textbook like all material things is made up of atoms, which are considered to be 99.9 percent empty space.
D) No. A textbook could only be considered to be 99.9 percent empty space if it were combusted.
