Question

60 drops fell from a burette, with the first and final readings representing the volumes in centimeters cubed. What was the average volume of one drop?

a) 60 cm^3
b) 2 cm^3
c) 1 cm^3
d) 0.5 cm^3

Answer 1

To calculate the average volume of one drop from a burette, subtract the initial volume reading from the final reading and divide by the total number of drops, which results in an average volume of 0.5 cm³ per drop.

Step-by-step explanation:

The question involves calculating the average volume of a drop of liquid from a burette based on the initial and final volume readings in centimeters cubed (cm³). If 60 drops caused the volume reading to change, one must simply subtract the initial reading from the final reading to find the total volume of the liquid that has been dispensed by the burette.

Then, the total volume is divided by the number of drops (60 in this case) to find the average volume of one drop. We don't have the specific readings, but as an example, if the initial reading was 10 cm³ and the final reading was 40 cm³, the calculation would be (40 cm³ - 10 cm³) / 60 drops, which simplifies to 30 cm³ / 60 drops, resulting in an average volume of 0.5 cm³ per drop.
