1. The analyzed mixture of H2SO4 and CuSO4 was brought to the mark in a volumetric flask with a capacity of 50.00 ml. Titration of a 10.00 ml aliquot with NaOH gave the following results:

VNaOH, ml 2.00 4.00 6.00 8.00 10.00 12.00 14.00 16.00 18.00 20.00
Electrical conductivity ω • 103 cm 7.0 6.0 5.1 4.2 3.0 3.0 3.0 3.5 4.0 4.5
Plot a titration curve and calculate the mass of H2SO4 and CuSO4 (g) in the mixture if T(NaOH) = 0.0003854.
