Calculate the moles of HCI that must be added to 100.0 mL of a solution that is 0.20 M in HCO₂H and 0.30 M in NaCO₂H to result in a pH of 2.95. You may assume there is no change in volume of the solution upon addition of HCI. The solution is at 25 °C where Ką for HCO₂H is 1.8 x 10-4 Enter your response in moles with no units, and use the correct number of significant figures.
