openlab.citytech.cuny.eduevident that osmosis had occurred in sacks 1, 3 and 4 because there was an increase in weight. This shows that the water molecules in the beakers had diffused into the sack, to an area of higher concentration of solutes. It was also observed that in sack 2, osmosis and diffusion had not occurred because there was no weight increase since
