Ground water sometimes contains traces of hydrogen sulfide, which has the odor of rotten eggs. Chlorine gas is used to purify the water for drinking. The resulting sulfur reacts with fluorine gas to give sulfur hexafluoride. The reactions are as follows: 

8 H₂S(aq) + 8 Cl₂(g) → 16 HCl(aq) + S₈(s) 

S₈(s) + 24 F₂(g) → 8 SF₆(g) 

Starting with 0.950 L of Cl₂ (STP) and excess fluorine gas, calculate:

(a) The mass of sulfur hexafluoride produced

(b) The volume of sulfur hexafluoride produced at STP

(c) The volume of aqueous 0.0265 M H₂S that reacted.
