I forgot to record the data in the lab.  Does anyone know how much 20 mL of water weights in a dialysis tubing bag? 20 mL of glucose solution? and 20 mL of salt solution?
Thanks!

The water can be calculated from its density:

20 mL H2O * 1 mg/mL = 20 mg

As far as the glucose and salt, you wouldn't be able to tell unless you knew the concentration of the solutions.
