The average atomic mass of Sn is 118.71 g/mol
the percentage of heaviest Sn is 5.80%
the given mass of Sn is 82g
The total moles of Sn will be = mass / atomic mass = 82/118.71=0.691
Total atoms of Sn in 82g =
the percentage of heaviest Sn is 5.80%
So the total atoms of = 5.80% X
Total atoms of = atoms
the mass of will be =
