WebOn Earth we measure mass (how much of a substance there is) by calculating weight (how heavy it is). Weigh each liquid in grams (make sure you subtract the weight of the beaker!) and then divide that number by the volume (number of milliliters) of the liquid. The answer is density in grams per milliliter. WebThe volume of the solution in the beaker could be found before and after the immersion of the bag by using a graduated cylinder. Based on your observations, rank the following by relative size, beginning with the smallest: glucose molecules, water, IKI, membrane pores, and starch molecules.
