010. Solving a chemistry problem

2. The mixture of HCl and CH3COOH to be analyzed was placed in a 50 ml volumetric flask and diluted with water to the mark. When titrating 10.0 ml of NaOH solution with a concentration of 0.1 mol/l (K = 1.104), the following results were obtained
V(NaOH), ml 7.0 8.0 9.0 10.0 11.0 12.0 13.0 14.0 15.0 16.0
k*103, cm/m 2.66 2.39 2.12 2.02 2.04 2.08 2.11 2.25 2.60 2.96
Construct a titration curve and determine the mass (g) of HCl and CH3COOH in the original solution.
