In a Potato Osmosis Lab if you were to submerge potato cylinders in different concentrations of sucrose solutions, and then find the final mass after 24 hours and then again after 48 hours. How would the mass change? Like if it decreased at the 24-hour mark due to osmosis (a potato cylinder in a high concentrated sucrose solution), would it be even smaller at 48 hours or larger due to equilibrium?

Mass - the decrease in the mass of the potato strip is due to the movement of water molecules outside of the plant cells. Water molecules in the cytoplasm are at a higher concentration than in the salt solution in the petri dish and so move along their concentration gradient out of the cells.
