Method 1. Using a size 6 core-borer, two potato chips of equal diameter were cut out of the potato. 2. These chips were cut to the same length of 4.5cm using a knife, taking care that no potato skin was included. 3. Five different concentrations of sugar solutions were prepared by mixing 50% sucrose solution and distilled water, using 100mL measuring cylinders. i. 0% sucrose solution 50mL of distilled water 0mL of 50% sucrose solution ii. 10% sucrose solution 40mL of distilled water 10mL of...
