You make two sucrose solutions, one of 0.5M and one of 2M and go out for lunch. When you return, you realize that you forgot to label the beakers! You remake the solutions, but give the undergrads in your lab an experiment to determine which beaker holds which solution. They fill two balloons, which are semi-permeable to water, but not to sucrose, with a 0.75M sucrose solution. One balloon is then placed in each of the unknown sucrose solution beakers. After several hours, they observe that the balloon in beaker 1 has swelled, while the balloon in beaker 2 has shrivelled. This indicates that beaker one contained the ________ sucrose solution, while beaker 2 contained the ________ sucrose solution.
A) 0.5M, 2M
B) 2M, 0,5M
C) unable to determine given the information provided.
