A. an ion
The atom gains a net electrical charge if the number of protons and electrons are not equal which makes it an ion.
Osmosis is a special kind of diffusion where solvent particles move through a semi permeable membrane from low concentration of solute to high concentration of solute.
so it depends upon
a) how much solvent is present : More the solvent on one side of semipermeable membrane more the movement of solvent particles on the other side of membrane
Take the 72 g and divid it by 6 which would equal 12 g each
