A 10.0mL sample of a weak monoprotic acid required 12.8mL of NaOH to reach the endpoint. If the weak acid had a concentration of 0.120M, what was the concentration of NaOH used? A 10.0mL sample of a weak monoprotic acid required 12.8mL of NaOH to reach the endpoint. If the weak acid had a concentration of 0.120M, what was the concentration of NaOH used? Solution volume of NaOH needed = 12.8 mL millimoles of acid = 10 x 0.120 = 1.2 at end point : millimoles of acid = millimoles of base 1.2 = 12.8 x M M = 0.0938 concentration of NaOH = 0.0938 M
