Explanation / Answer

Remember coke is always denser than diet coke, try and place coke can of same volumes of the two types one sinks the other does not. This is due to the low sugar content in diet coke, as the name sugeests, the mass decreases consequently density decreases.

While taking measurements of volume, Beaker is always out of consideration for precision as it is the least precise glassware, graduate cylinders are meant for measurements of volume and give better results.

When we compare a burete to a measuring cylinder, burete is always preciser than a cylinder because of per drop control that can be achieved in the burette. If pipete was to be an option that would be even more precise.

As the data reveals the least standard deviation is by burete,in diet coke.

For the case of regular coke, due to increased sugar the density of coke goes up and drop size reduces, consequently we end up releasing less volumes and deviations are high.
