Question

volume of water in a burette is 35 ml. find the volume of a drop of water if volume of water in the burette is 5ml in 50 drops of water is drained out.​

Answer 1

by counting the amount of droplets it takes to fill a volume of 10ml.

And yes it was a slow process, but i ended up with 256 droplets of water per 10ml roughly.

Then i just divided 10 by 256 to find the average volume of a water droplet:

10 ml/256=0.0390625… ml

Then after that i rounded the answer and got 0.05 ml.

Answer 2

Answer: AMOUNT OF WATER= 35ml

              and 5ml of water is drained out

Explanation: so, volume of a drop of water = (35 - 5) / 50

                                                                           = 30 / 50

•                                                                             = 0.6 ml
