Answer to Question #103138 in General Chemistry for Jija

Question

Using the Average volume of KOH (15.7mL) (and then it said 0.05 M for KOH), calculate the concentration of your vinegar solution "in % m/V". (In the flask at the bottom of the burette there was 10mL of acetic acid)

Answer 1

CH3COOH + KOH = CH3COOK + H2O

15.7 x 0.05 / 1000 = 0.000785 mol KOH

0.000785 x 1000 / 10 = 0.0785 mol/L.
