Find the mass of carbon that contain the samme number of atoms as contained by 560g of iron (atomic mass=56).

Explanation

No. of Featoms present in 1 mol of 56g of
`Fe=6.022xx10^(23)`
`therefore`Number of Fe-atoms present in 560g of Fe
`=6.022xx10^(23)xx(560)/(56)=6.022xx10^(24)`
Mass of `6.022xx10^(23)` number of C-atoms=12g
`therefore`Mass of `6.022xx10^(24)` number of C-atoms=120g.
