An analyst is directed to prepare accurately to four significant figures 100mL of a solution of Na2CO3 that is around 0.25 M. The laboratory supervisor provides a solution of 4.021M Na2CO3, and some pure, solid Na2CO3, and tells the analyst to proceed by whichever method is easier. Give specific outline as to how you would prepare the solution by two different methods, one by dilution and one by weighing pure chemical. (Show calculation, what type of glassware is used, include size and kinds of pipets and flasks)
