Problem

A laboratory sample of aqueous H2SO4\text{H}_2\text{SO}_4 at 25\,∘^{\circ}C has a recorded pH of 0.92 (two significant figures). Assuming both protons from the acid dissociate completely, what is the best estimate of the molarity of the original acid, expressed with the correct number of significant figures? (a) 0.12 M0.12\,\text{M} (b) 0.30 M0.30\,\text{M} (c) 0.060 M0.060\,\text{M} (d) 0.024 M0.024\,\text{M}
