Calculating K_c for an equilibrium reaction

Calculation:

1.    Calculate the number of moles of NaOH that neutralised both acids in the titration.

2.    Use the ratio to calculate the number of moles of both acids in the titration.

3.    Calculate the number of moles of both acids in the original 100cm³ flask.

4.    Calculate the number of moles of HCl catalyst from activity sheet 17.

5.    Calculate the number of moles of CH₃COOH at equilibrium.
