Answer 1

1. 80/200 = 0.4 g/ml

2. 2/40 = 0.05g/ml

3. 35/100 = 0.35g/ml

4. 25/10 = 2.5g/ml

5. 50/100 = 0.5g/ml

6. out of the dialysis bag because the dialysis bag contains 2.5g/ml of glucose where as the beaker contains 0.5g/ml of glucose. Diffusion is always from higher concentration to a lower contration, therefore glucose goes out of the dialysis bag and into the beaker

7. water will go into the dialysis bag because osmosis is the spontaneous movement of water (or solvent) moving from an area of lower concentration of solute to higher concentration of solute, and there is more glucose inside the dialysis bag than the outside (i.e. the breaker)

by the way, is this science 9?
