Unformatted text preview: 1. Each group should cut size pieces of celery, each about 3 cm long. Weigh each piece, and record its mass in Table 2. 2. Obtain six paper clips of the same color (each group will have a different color clip). Attach a clip to each of your celery pieces, keeping track of which piece will go into which solution. 3. Place one piece in each of the six provided salt solutions, ranging from 0% to 12% salt. 4. After one half hour, remove your celery pieces, weigh them and record the masses in table 2. 5. Create a graph of percent mass change on the y-axis and salt concentration on the x-axis. The salt concentration at which 0% mass change occurs corresponds to the solute concentration of the celery cells. In other words, look for the x-intercept (where percent mass change is zero). 6. What is the approximate solute concentration in the celery cells? ______________...
