The molecules are ${\mathrm{SOF}}_4$, ${\mathrm{SF}}_4$, ${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_8$, ${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_7$, ${\mathrm{SO}}_2{\mathrm{Cl}}_2$, ${\mathrm{S}}_3{\mathrm{O}}_9$.

1. ${\mathrm{SOF}}_4$ (Thionyl tetrafluoride): Hydrolyzes to ${\mathrm{H}}_2{\mathrm{SO}}_4$ and $\mathrm{HF}$.

${\mathrm{SOF}}_4+2{\mathrm{H}}_2\mathrm{O}\to {\mathrm{H}}_2{\mathrm{SO}}_4+4\mathrm{HF}$

2. ${\mathrm{SF}}_4$ (Sulfur tetrafluoride): Hydrolyzes to ${\mathrm{SO}}_2$ and $\mathrm{HF}$.

${\mathrm{SF}}_4+2{\mathrm{H}}_2\mathrm{O}\to {\mathrm{SO}}_2+4\mathrm{HF}$

3. ${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_8$ (Peroxodisulfuric acid): Hydrolyzes to ${\mathrm{H}}_2{\mathrm{SO}}_4$ and ${\mathrm{H}}_2{\mathrm{O}}_2$.

${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_8+2{\mathrm{H}}_2\mathrm{O}\to 2{\mathrm{H}}_2{\mathrm{SO}}_4+{\mathrm{H}}_2{\mathrm{O}}_2$

4. ${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_7$ (Pyrosulfuric acid/Oleum): Hydrolyzes to ${\mathrm{H}}_2{\mathrm{SO}}_4$.

${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_7+{\mathrm{H}}_2\mathrm{O}\to 2{\mathrm{H}}_2{\mathrm{SO}}_4$

5. ${\mathrm{SO}}_2{\mathrm{Cl}}_2$ (Sulfuryl chloride): Hydrolyzes to ${\mathrm{H}}_2{\mathrm{SO}}_4$ and $\mathrm{HCl}$.

${\mathrm{SO}}_2{\mathrm{Cl}}_2+2{\mathrm{H}}_2\mathrm{O}\to {\mathrm{H}}_2{\mathrm{SO}}_4+2\mathrm{HCl}$

6. ${\mathrm{S}}_3{\mathrm{O}}_9$ (Cyclic sulfur trioxide trimer): Hydrolyzes to ${\mathrm{H}}_2{\mathrm{SO}}_4$.

${\mathrm{S}}_3{\mathrm{O}}_9+3{\mathrm{H}}_2\mathrm{O}\to 3{\mathrm{H}}_2{\mathrm{SO}}_4$

All 5 molecules (${\mathrm{SOF}}_4$, ${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_8$, ${\mathrm{H}}_2{\mathrm{S}}_2{\mathrm{O}}_7$, ${\mathrm{SO}}_2{\mathrm{Cl}}_2$, ${\mathrm{S}}_3{\mathrm{O}}_9$) produce sulfuric acid upon complete hydrolysis. ${\mathrm{SF}}_4$ does not.

The number of molecules is 5.
