Question

The equilibrium constant (Ka) for Reaction 3 at 25 °C is 1.80 × 10−4 mol dm−3. Calculate the equilibrium concentration of hydrogen ions if the concentration of formic acid at equilibrium is 0.00500 mol dm−3. (Show all of your working and give your answer to three significant figures, in correct scientific notation.)
Oh yeah! Those values apply to this equation:

HCOOH(aq) <-----> H^+ (aq)+ HCOO^-(aq)
whats the answer
