Question: how many atoms are present in 1 mole of nacl?
Answer: Since 1 molecule contains 1 atom each of Na and Cl, 1 mole of NaCl will contain 1 mole each of Na and Cl. We know that 1 mole of anything contains an Avogadro's number of atoms or 6.023 x 10^23 atoms. Thus, 1 mole of NaCl will contain 6.023 x 10^23 atoms each of Na and Cl, or a total of 12.046 x 10^23 atoms.
