Here are the solutions for the questions based on the provided image. a) Complete table II by filling in the missing values. Step 1: Calculate the missing values for each experiment. Experiment 1: Given: Volume of solution X used = 26.3 cm^3. Assuming the initial burette reading for the first trial is 0.0 cm^3. Final burette reading = Initial burette reading + Volume of solution X used = 0.0 cm^3 + 26.3 cm^3 = 26.3 cm^3. Experiment 2: Given: Final burette reading = 47.7 cm^3, Initial burette reading = 21.5 cm^3. Volume of solution X used = Final burette reading - Initial burette reading = 47.7 cm^3 - 21.5 cm^3 = 26.2 cm^3. Experiment 3: Given: Final burette reading = 29.4 cm^3, Volume of solution X used = 26.2 cm^3. Initial burette reading = Final burette reading - Volume of solution X used = 29.4 cm^3 - 26.2 cm^3 = 3.2 cm^3. Step 2: Fill in the completed table. | Experiment | 1 | 2 | 3 | |---|---|---|---| | Final burette reading | 26.3 | 47.7 | 29.4 | | Initial burette reading | 0.0 | 21.5 | 3.2 | | Volume of solution X used (cm^3) | 26.3 | 26.2 | 26.2 | b) Determine the average volume of solution X used. Step 1: Identify concordant titres. The volumes of solution X used
