Answer:
hey mate here is your answer
Explanation:
Atoms, molecules and ions are the basic units in chemistry because these are involved in chemical reactions. A definite number of atoms, ions or molecules of one substance reacts with a definite number.
A mole is a unit for counting microscopic particles like electrons, atoms, ions, molecules etc. Atomic masses or molecular masses have no unit because they are relative to the mass.
Atomic weight in gram = gram - atom ( 1 G- atom)
Molecular weight in gram = gram- molecular.
