What is the pH of a 0.1 M sulfuric acid solution? (did you know sulphuric is an alternative spelling?)

H $_2$ SO $_4$ + H $_2$ O $\longrightarrow$ HSO $_4^-$ + H $_3$ O $^+$ , K $_{a1}$ = 1.0 x 10 $^{3}$

HSO $_4^-$ + H $_2$ O $\longrightarrow$ SO $_4^{2-}$ + H $_3$ O $^+$ , K $_{a2}$ = 1.2 x 10 $^{-2}$
