Having trouble grasping these problems. Calculate the pH of a Solution with 32.9g Formic acid HCOOH per Liter?

now I calculated the Molarity to be 0.174 M I THINK thats the initial because it comes from the 32.9g and I dont beleive this is a strong acid. So my equation is HCOOH + H2O <> H3O + HCOO- SO the initial concentrations would be HCOOH =0.174 H3O...
