Question

Explain why the percentage change in mass is more useful than the change in mass when analysing the results in Table 1.1.​

Answer 1

Answer:

The difference in mass does not deal with the proportional aspect of the solutions, making the results less accurate. The percent was calculated to give an exact difference, along with considering the quantities of solution.

Answer 2

Weight change is even more effective than weight change when analyzing results in Table 1.1. :

If it reaches 1kg and changes by 1g, that is not very important.

Thus, the percentage of weight is always used to indicate the magnitude of the change, compared to the available weight.

Percentage change in weight is expressed more often than in variable weight change in order to establish a comparative integration.

Percentage change in weight/height is calculated using the following calculation:

Potato cylinders soaked in clean water or weak sucrose solutions will increase in size/length as the water will move from a highly concentrated area (except potato cells) to a low concentrated area (inside potato cells).
