Analysis

The trend that my graph and results show is that when the potato was placed in a solution that had a higher concentration than the chip itself, the potato lost weight (0.4, 0.6, 0.8 and 1.0 molars). In the same way when the potato chip was placed in a solution that had a lower concentration than itself, the potato chip gained weight (0.0 and 0.2 molars).

For my results I calculated the percentage gain/loss in weight using the following formulae:
Average change in weight/weight at start times 100

The graph slopes downwards. This means that the percentage gain and loss in weight and concentration are not directly proportional because the line is not straight and does not pass through the origin. However, there is a pattern on my graph, and this is, as the concentration of the solution increases, the percentage change in weight decreases.

From the line of best fit that has been added in, it can be seen that all of my points are very close to the line if not......
