The aim of this experiment was to find out how many sugar did the potato include, how many sugar did we have every day by eating the potato. To know the sugar that includes in the potato we have to compare the mass of the potato before and after the experiment with different concentration of sucrose solution. We went through our procedure, put the result into the data table and calculate the percent change to the graph. And get the osmolarity bass on the graph we have.
The mass of the before the experiment was ranged from 8.520 g to 18.46g. The weight between each of the potato was different because our goal was to find the percent change in mass, which made the mass of the potato don’t have to be the same. The mass after the experiment was ranged from 7.280g to 15.05g. We could tell the solution concentration in 0.0M, and 0.2M make the potato’s mass increased which making the potato hypotonic. The mass decreased in the solutions of 0.4M, 0.6M, 0.8M, and 1M making them hypertonic.

We all know the osmolarity is when the average percent of mass become zero, so we put y = 0 and get the x = 0.3932M. By the calculation, we can know the osmolarity of sucrose within the potato is 0.3932M because the solution is isotonic.
According to all the data table, graph, and the calculation we have for this experiment, our hypothesis “If the potato placed in a sucrose solution 0M or 0.2M, then it will be hypotonic. If the potato placed in a sucrose solution ranging from 0.4M to 1M, then it will be hypertonic.” is supported by the result of the
