If you pull out 50 mL of water from each solution which solution will weigh more?
They will have an equal weight.
Solution A has 50 mL of water and a solid. Solution B has 100 mL of water and a solid. How can you use a balance to tell with solution is more concentrated?
A. just put them both on the balance. The heavier one is more concentrated.
B. Pull out 50 mL from Solution B then put them both on the balance.
B
Solution A is heavier than solution B, but they both have the same amount of water. Why is solution A heavier?
Because Solution A is more concentrated.
Solution A has more solute.
When water evaporates into the air does the water become the solute or the solvent?
Water becomes the solute because it dissolves into the air.
