When the pH = 5 for this chemical equation, NaC2H3O3 (aq) →Ha+ (aq) +C2H3O3- (aq):
1. Calculate the mole ration of conjugate acid to conjugate base for a buffer, by using the Henderson-Hasselbalch equation.
2. Calculate the mole of the conjugate base, when the concentration of acid is 0.10 M and the total volume is 2L.
