Answer : The correct option is, (C) 0.6 ml
Explanation : Given,
Initial volume of solution in the burette = 32.3 ml
Final volume of solution in the burette = 32.9 ml
As the liquid is colorless. So, we are taking the lower meniscus for the correct reading of the solution.
Now we have to calculate the total volume of solution that was dispensed from this burette.

Now put all the values in this formula, we get the total volume of solution that was dispensed from this burette.

Therefore, the the total volume of solution that dispensed from this burette was, 0.6 ml
