Answer:
➩The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present
➩Atomic mass is the mass of an atom and is given in a.m.u. (atomic mass unit). However, a molar mass is the mass of one mole atoms or molecules and is given in grams. one mole is equal to Avogadro's number ( NA=6.022×1023 ) atoms or molecules.
