a) H b) D C)T D) He

Answer Posted / ulab

One mole of 'X' contains 6.023 × 10 power 23 atoms

Mole = Weight / Molecular weight

1g of hydrogen, Deuterium, Tritium, Helium has 1, 0.5, 0.33,
0.25 mole of atoms respectively.

So one gram of hydrogen has more number of atoms among the
other i.e)6.023 × 10 power 23 atoms
