The pH of a 0.401 mol/L solution of sulfurous acid is 1.16 (used as an example, your value may be different). Based on this evidence, the Ka for sulfurous acid is?

They're asking for Ka though (answer is highlighted). You're giving the concentration, watch out for that. But to answer your question, as per the attachment, it's identical to what I found too for the hydronium concentration.
