Complete table II by filling in the missing values and determine the average volume of solution X used.

• Experiment 1:
  • Given: Volume of solution X used = 26.3 $\text{cm}^3$.
  • Assuming the initial burette reading for the first trial is 0.0 $\text{cm}^3$.
  • Final burette reading = Initial burette reading + Volume of solution X used = 0.0 $\text{cm}^3$ + 26.3 $\text{cm}^3$ = 26.3 $\text{cm}^3$.
• Experiment 2:
  • Given: Final burette reading = 47.7 $\text{cm}^3$, Initial burette reading = 21.5 $\text{cm}^3$.
  • Volume of solution X used = Final burette reading - Initial burette reading = 47.7 $\text{cm}^3$ - 21.5 $\text{cm}^3$ = 26.2 $\text{cm}^3$.
• Experiment 3:
  • Given: Final burette reading = 29.4 $\text{cm}^3$, Volume of solution X used = 26.2 $\text{cm}^3$.
  • Initial burette reading = Final burette reading - Volume of solution X used = 29.4 $\text{cm}^3$ - 26.2 $\text{cm}^3$ = 3.2 $\text{cm}^3$.
