The results were presented on a graph against the percentage change in mass against the concentration of sucrose molarity
The molar concentration of the potato cell is 0.2M
Explain how you would determine the molarity of a potato
To determine the molarity of a potato, you would first need to conduct an experiment similar to the one described above. In this experiment, you would prepare a series of sucrose solutions with known molar concentrations. Then, you would measure the initial mass of a potato slice, immerse it in each sucrose solution for a certain amount of time, and then measure the final mass.
By calculating the percentage change in mass for each sucrose solution, you can plot a graph of percentage change in mass against the concentration of sucrose molarity. By comparing the behavior of the potato slice in the sucrose solutions to the behavior of the known concentrations, you can determine the molarity of the potato cell.
In the given data, the molarity of the potato cell is determined to be 0.2M based on the percentage change in mass. The concentration where the percentage change in mass matches that of the potato cell is the molarity of the potato.
