Question

what is an advantage and a disadvantage of each volumetric method of measurement, which is the most accurate. When transfering the water from the graduated cylinder to ther beaker, does this introduce a systematic and/or error into a mass measurement?

water from faucet 50ml beaker and weighed

graduated cylinder 5ml water transfered to a 50ml beaker and weighed

graduated cylinder 50ml water transfered to a 100ml beaker and weighed

volumetric pipet water transfered to 50ml beaker and weighed

buret to beaker water transfered to 50ml 50 beaker and weighed

Answer 1

Solution :-

The most accurate methos for the volumetric measurment are as follows

volumetric pipet water transfered to 50ml beaker and weighed

buret to beaker water transfered to 50ml 50 beaker and weighed

because volumetric pipet and burret are caliberated therefore they measure the exact volume of the liquids

The other two methods involving the graduated cylinders are the not advantageous methos because the graduated cylinder is not caliberated therefore it can have some error in the volume measurment thereofre it will have little difference in the measured volume of the liquid.

So the advantage for the first two method is that we can measure the aproximate volume of the liquid and disadvantage is that the measurment is not exact.

And advantage for the other two method is they used to measure the exact volume of the liquids and minimizes error.
