Please help on this question

You fill each of three (20 ml) dialysis bags half full with one of these substances:

5% by weight of glucose in distilled water
5% by weight of egg albumin (protein) in distilled water
5% by weight of glass bead (one glass bead) in distilled water

The dialysis bag is permeable to water but impermeable to glucose, albumin, and glass bead.

A.) if the final weight of each bag is 10g, how many grams of glucose, albumin, and glass bead were added to each bag?

5 % is weight/volume or 5 g for 100 ml of solvent. What is the mass of 100 ml of the liquid here?
Then consider the dilution factor and you have your answer.
