In which one of the following cases the number of hydrogen atoms is more ?
Two moles of `HCl` or One mole of `NH_(3)`

Explanation

1 Mole of `NH_3` contains 3 moles of H-atoms
`=3 xx N_(0)` atoms
1 mole of HCl contains 1 mole of H-atoms .
`therefore` 2 moles of HCl will contain 2 moles of H-atoms
` = 3 xx N_0` atoms
Thus, 1 moles of `NH_3` contains larger number of H-atoms than 2 moles of HCl.
