2. The analyzed mixture of H2SO4 and CuSO4 was brought to the mark in a 50.00 ml volumetric flask. When titrating a 10.00 ml aliquot with NaOH solution, the following results were obtained:

VNaOH, ml 2.00 4.00 6.00 8.00 10.00 12.00 14.00 16.00 18.00 20.00
AE • 103 Cm 6.5 5.4 4.4 3.4 2.5 2.5 4.2 6.5 8.9
Plot a titration curve and calculate the mass of H2SO4 and CuSO4 (g) in the mixture if T(NaOH) = 0.0003854.
