Homework Help: physiology/ anatomy

Posted by kira on Friday, September 7, 2012 at 7:58pm.

I'm doing a lab about osmosis/ diffusion. We put a 2 molar solution of NaCl into a dialysis bag and submerse the bag in water, weighing the bag after 15 minute increments for an hour. I need help explaining why the weight of the bag would fluctuate (EX. 6 grams -> 7 grams -> 6 grams) rather than just increasing in weight or remaining the same.
