Question
Volume of a Drop Delivered from a Buret The smallest practical volume that a beginning user can deliver from a buret is 1 drop. Solutions from burets are generally delivered until a signal is observed in the target vessel. We try to control the delivered volume to be within 1 drop of the first detection of the signal. This part of the exercise is intended to provide the user of the buret with a sense of the volume, and therefore, the precision represented by that drop. The following data are collected in determining the average volume of a drop delivered from a 50 mL buret: What is the average volume of a drop in mL? Enter Your Answer: 0.04 ml. To the nearest integer, how many drops are in 1.00 mL of water? [It is useful to remember this number to estimate potential errors in future exercises.] Enter Your Answer: 25Explanation / Answer
Answer:
From the given values change in volume v=2.55 ml (3.99 ml-1.44 ml=2.55 ml)
2.55 ml equal to 56 drops, then one drop=2.55/56=0.04554 ml.
The average volume of drop in ml=0.04554 ml
In 1ml of water the number of drops =56/2.55=21.96 drops=~22 drops
