The conclusion is that water has moved from the beaker into the bag by osmosis because concentration of solute in the beaker is lower than that in the bag.
<h3>What is osmosis?</h3>
Osmosis is the movement of water molecules across a semipermeable membrane from a solution of low solute concentration to one of high solute concentration.
The concentration of solute in the beaker is lower than that in the bag, therefore, water will move from the beaker into the bag by osmosis.
In conclusion, the solution in the beaker is of lower solute concentration than in the bag.
