Why do you need to dry the potatoes before weighing them?

The potato strips were then carefully bloated using tissue paper without squeezing them to remove water from the external part. Their respective weights were measured and noted. Subsequently, they were placed in the prepared sucrose solutions. After forty-five minutes the strips were removed, bloated, and reweighed. See more Osmosis refers to a special form of transport of water molecules across the plasma membrane. It involves water molecules movement through a selectively permeable … See more An increase in the concentration of sucrose solution results in a subsequent decrease in the weight of potato strips. See more To determine the relationship between an increase in sucrose concentration and the resulting effect on the weight of potato strips. See more For this experiment, the varying sucrose concentration solution is the independent variable.
