An unusual category of acids known as superacids, which are defined as any acid stronger than 100% sulfuric acid, can be prepared by seemingly simple reactions similar to the one below. In this example, the reaction of anhydrous HF with SbF₅ produces the superacid [H₂F]⁺[SbF₆]^-:

a. What are the molecular structures of all species in this reaction? What are the hybridizations of the central atoms in each species?

b. What mass of [H₂F]⁺[SbF₆]^- can be prepared when 2.93 mL anhydrous HF (density = 0.975 g/mL) and 10.0 mL SbF₅ (density = 3.10 g/mL) are allowed to react?
