Why is it that when I calculate the pH of this particular solution I get 3.50 when it's saying the pH is 2.79?

pH is -log(Ka).
Ka=[hydronium concentration][aion concentration]/[weak acid concentration]
So that's Ka=(1.63*10^-3)(1.63*10^-3)/(8.37*10^-3)
But like I said above this gets me the wrong pH. I feel like there's some initial concentration as opposed to equilibrium concentration fuckery going on here. I don't think I need to make an ICE table, it looks like the software is doing the work for me.
