molar mass of iron =56g/mol
molar mass of aluminium = 27g/mol
no. of moles present in 50g of iron.= 50÷56=0.8928
no.of moles present in 50g of aluminium = 50÷27= 1.8518
atoms present in iron = 0.8928 ×(6.023×10^23) = 5.3773×10^23 atoms
atoms present in aluminium = 1.8518×(6.023×10^23) atoms.=11.15×10^23 atoms
thus, aluminium will have more number of atoms.
