Number of atoms in 558.5 gm Fe (At.wt of Fe = 55.85 g mol^(-1)) is

1.	Number of atoms in 558.5 gm Fe (At.wt of Fe = 55.85 g mol^(-1)) is
Answer» TWICE that in 60 g carbon `6.023xx10^(22)` Half that in 8g He `558.6xx6.023xx10^(23)` Solution :moles `=(558.5)/(55.85)=10=6xx10^(24)` ATOMS `60g C=(60)/(12)=5` moles `therefore` atoms = twice in 60 gc
