2. (a). Student A might conclude that although his method does not give a very precise result, the method provides pretty accurate results.
(b). The strength of the result may be talked about by stating that although the method is not precise, it has a interval which contains the real value of the density.
Table 1 shows information relevant for calculations so it would be shown in supporting information but Table 2 includes raw data and so will not be include in supporting information but only the difference of mass will be stated in the supporting information section. Table 3 includes information that shows the reader the work that was done so it would be shown in the supporting information section.

(b). Table 1 shows the information regarding …show more content…
Only the difference in mass can be mentioned in the supporting information.

(c). We can conclude that the presence of other hydrates affects the average waters of hydration. We can also conclude that it would be better to avoid heating and prolonging the dissolution.

These conclusions can be supported by the data. We had 1.42 waters of hydration which is not the literature value. So its is very likely that there a lot of different hydrates present in the product. The low yield can be accounted for by taking decomposition into account because all other methods used after dissolution are pretty accurate for quantitative analyses.

The main limitation to the conclusion that better method for dissolution may be needed. Even a little bit of heating can cause some decomposition and no heating could cause the dissolution to take a long time.

(d). The main objective of the experiment is to synthesis ammonium decavanadate hexahydrate and analyze the product using quantitative methods of titration.
The motivation for the experiment is to learn about the redox titration methods which are pretty accurate for quantitative analyses and to learn to synthesis a difficult
