Answer:
air is a group of different gases and gas is loose bound atoms of an element
Explanation:
Answer:
molecule is a group of atoms bonded together representing the smallest fundamental unit of a chemical reaction
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 =
