WebFirst, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. Finally, divide the number of moles of acid by the given volume of the acid solution to find the concentration. WebJul 13, 2024 · First, let's find out, how many gram of benzoic acid is in 1 liter of 0,1191M solution. 1 mol of Benzoic acid is 122 gram. But we have 0.1191 mol or 14,53 gram. That amount is in 1 liter, but we have 25 ml. So, 14,53 gram x 0,025 l=0.3632gram benzoic acid. Now, we can find how many gram NaOH . (0.363x40):122=0,119 gram.
