Before starting the freeze-drying process, the weight of the test tube, Wi which is 15.33g and test tube with microbial cell pellets, Ww which is 34.94g were weighed using an electronic balance. Plus, final weight of the beaker with test tube and cells is 70.35g. Then, the average amount of water removal and average cell yield were calculated by using the formulas given which were 9.81g and 0.5001. As a conclusion, there was 9.81g of water had been removed by using the technique freeze-drying for 24 hours by using a freeze dryer. Question: 1.From this statement, please explain what process actually has happened during this freeze-drying method. 2.Make a clear conclusion that can made from this experiment.(explain briefly)
