The blank should be filled with the average titre volume from your accurate titrations. This value is obtained by averaging the two (or more) concordant titre values recorded in the "Accurate" columns of the table. For example, if your two accurate titre values were 20.10 cm^3 and 20.05 cm^3, the average would be: Average titre = 20.10 cm^3 + 20.05 cm^32 = 20.075 cm^3 You would then round this to an appropriate number of significant figures, typically two decimal places for burette readings, e.g., 20.08 cm^3. Since the table is empty, I cannot provide a numerical answer. You need to perform the experiment and record your results. Hence Average accurate titre cm^3 of Na_2S_2O_3 reacted with 25 cm^3 of CuSO_4. That's 2 down. 3 left today — send the next one.
