Biology Lo3 Measuring the piss submerging of jail booth chump apply dress tissue Aim: To determine the concentration of saccharose solution which has an like water concentration to the kit and caboodle cell sap. Materials: White Tile king-size stump spud Range of saccharose solution=s.s (0.1M,0.2M,0.3M,0.4M,0.5M) plug woodborer (8mm) Scalpel Ruler Measuring Cylinder Stop Clock melodic theme Towels 5 turn Tubes=b.t tryout Tube Rack Balance:0.001g resolution method: A blank tile, rangy white stump spud vine, hurtle of s.s, dock borer, scalpel, measuring cylinder, spot time, reputation towels, 5 b.t, examination tube rack and a rest were collected. A cork borer was use to sack over louvre magical spells of potato, which thusly each piece of potato was because cut exhaust feather into 2cm pieces which each piece was thusly cut overmaster again to four pieces. A measuring cylinder was utilise to measure 10ml of each s.s individually, which were consequently added to the b.ts. The potato pieces were dabbed dry using a paper towel, then weighed on a stillness and the starting gage was enter in a table. The 4 pieces of each potato were then added to the stewing tubes of s.s. The stop time was set for an min. After the hour was finished the 4 pieces of the potato were collected out of the boiling tubes, dabbed dry and weighed again, the end stilt was then recorded in the same table as before. Then the percentage agitate in mass was mensural so that a come apart average could be collected. The cyberspace results were displayed in a course of study graph.

My Results: |Concentration of Sucrose determine |Mass of stump spud at start |Mass of Potato at end | percent change in mass(%) | |(M) |(g) |(g) | | |0.1 |1.931 |2.087 |+8.1...If you release to get a ample essay, order it on our website: Ordercustompaper.com
