Solution

I believe you want to ask how to calculate the amount of water either absorbed or lost by raisins in the mentioned solutions.
It is important to weigh the raisins before putting them in the solution.
i. In case of water being absorbed, we subtract the initial weight of the raisin by the final weight to determine the weight of water absorbed.
ii. In case if water being lost, we subtract the final weight of the raisin (which is less than the final weight) from the initial weight to get the weight of water lost.
