How many moles of naoh must be added to hcooh(aq)

Reference no: EM13689294

Question- How many moles of NaOH must be added to 0.400 L of 0.177 mol/L HCOOH(aq) to obtain a solution with pH=3.5? Assume the temperature is 25oC. (For HCOOH, pKa=3.74 at 25oC).

How do I yet start setting this up? Thank you
