Here's how it's determined:

* Silver: The symbol for silver is Ag.

* Bisulfate: This is the anion formed when one hydrogen atom is removed from sulfuric acid (H₂SO₄). The bisulfate ion has the formula HSO₄⁻.

Therefore, combining the silver cation (Ag⁺) and the bisulfate anion (HSO₄⁻) results in the formula AgHSO₄.
