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

if all the potatoes cores allowed to dehydrated, by sitting in the open air would the water potential of the potato cell decrease or increase. Why?

If the potato cores are allowed to dehydrate by sitting in the open air, the water potential of the potato cell would decrease. This is because the water potential is a measure of the potential of water to move from one place to another, and as the potato cores lose water and dehydrate, there would be a decrease in the amount of free water molecules available in the cell. This would result in a decrease in the water potential of the potato cell.
