Question

what is the maximum number of atom ?

Answer 1

Number of atoms = number of moles 
× Avogadro’s number (N A) 
⇒ Number of atoms in 24 g C = 24/12×N A= 2N A 
Number of atoms in 56 g of Fe 
= 56/56N A = N A 
Number of atoms in 27 g of A1 = 27/27N A = N A 
Number of atoms in 108 g of Ag = 108/108N A = N A 
Hence, 24 g of carbon has the maximum number of atoms.
