Use the Henderson-Hasselbalch equation to calculate the pH of each solution:
a solution that contains 1.05% C2H5NH2 by mass and 1.10% C2H5NH2Br by mass
a solution that contains 1.05% C2H5NH2 by mass and 1.10% C2H5NH2Br by mass

Percent by mass means grams solute/100 g solution. Since each solution is approximately the same, I would ignore the small difference and convert 1.05 g and 1.10 g to moles and substitute moles into the HH equation. Show your work if you get stuck.
