The water-containing tubing was then rinsed, weighed (4.774g) and put into a beaker that contained sugar water. After about an hour, the tubing was removed from the beaker, rinsed and reweighed (4.316g). The determined masses are a. consistent with the expected osmosis that should have occurred b. not consistent with the expected osmosis that should have occurred; the tubing probably leaked c. not consistent with the expected osmosis that should have occurred; the tubing was probably put into pure water rather than sugar water d. not consistent with the expected osmosis that should have occurred; no cause is apparent e. no correct responseDO NOT ANSWER IF YOU ALREADY ANSWERED THIS.
