Will changing sucrose concentrations change the mass of the potato?

Yes, through a process called osmosis. Osmosis is the diffusion of water across a cellular membrane. Water flows from high concentrations to low concentrations. The mass of the potato will change based on the molarity of the solution it is placed in. CHEMISTRY REFRESHER: molarity is the amount of moles of a substance per liter(of water). If the potato is placed in a solution with a lesser molarity than itself(the solution has less glucose than the potato) then we would expect for the potato to gain water. This is because there is a greater concentration of water outside of the cell wall, so water enters the cell in order to obtain equilibrium. Using the same reasoning we would expect for the potato to lose water if it is placed in a solution of higher molarity

Why is it that when you put a potato in a high concentration of sucrose solution does its weight decrease?
This is because the potato, which is mostly water, is in a hypertonic solution (a solution with less water and more solute --here, sucrose-- than the potato). Since the solutions want to reach equilibrium (equal amounts of sucrose and water in both the solution and the potato), water diffuses out of the potato and sucrose diffuses into it. The potato loses its water weight, and sucrose doesn't replace the weight lost, the potato weighs less.
What is the sucrose molarity of a potato?
The potato is naturally very low in sugars. Although a potato contains three types of sugars; sucrose, fructose and glucose, the average potato is less than one percent sugar.
Which piece of equipment is the best foe measuring the change in the mass of potato slices after placing them in different concentrations of salt water?
Graduated cylinder
Is boiling a potato a physical change?
Yes, your changing the texture of the inside from a more harder on to that of a bit more softer.
What plants produce sucrose?
beet root, sugar cane and sweet potato produce sugar.
Where is the disaccharide sucrose found in a potato plant?
The Disaccharide Sucrose found in a potato plant is in the flesh of the potato. The potato is nearly 100% starch and carbohydrates that produce sugars in the body.

How does glucose get to potatoes in potato plants?
Potato tubers make glucose by degrading sucrose (cane sugar). Sucrose is the end-product of photosynthesis and is transported from the leaves through the phloem to the tuber.

What can you conclude about the permeability of potato cytoplasm with respect to sucrose and water molecules?
H20 molecules can pass through the membrane freely, however sucrose molecules are too large.
Characteristics of a substance that can be measured with out changing the substance equals?
potato
Is a potato a chemical or physical change?
A potato is a substance and not a change of any description.
What plants produce sucrose?
beet root, sugar cane and sweet potato produce sugar.
Does potato chips have starch?
Potato chips are made from potatoes, which is a very starchy food. Starch is made up of glucose. In this sense, potato chips should indeed have small amount of glucose present.
