Explanation:
(a) As per the mole concept, one mole of any atom contains atoms or molecules, that is, Avogadro's number of atoms.
Therefore, 1 mole of =
molecules
= molecules
1 mole of =
molecules
= molecules
1 mole of =
molecules
= molecules
Hence, there are equal number of molecules present in the given atoms.
(b) Mass of each given atom will be calculated as follows.
Mass = no. of moles × molar mass
As one molecule of contains 2 atoms of hydrogen.
So, mass of 1 mole of =
= 2.016 g
mass of 1 mole of =
= 31.996 g
mass of 1 mole of =
= 37.996 g
Thus, we can conclude that has the greatest mass.
