| That is
still incorrect.
By looking at the formula,

In 1 mole of sulphuric acid, there are
- 2 moles of hydrogen
atoms,
- 1 mole of sulphur atoms
and
- 4 moles of oxygen atoms.
So, in 3 moles of sulphuric acid, there
will be
- 2 x 3 = 6 moles
of hydrogen atoms,
- 1 x 3 = 3 moles
of sulphur atoms and
- 4 x 3 =12 moles
of oxygen atoms.
