Question

The figures below are molecular level representations of four aqueous solutions of the same solute. Arrange the solutions from most to least concentrated.

Short answer

The order from most concentrated to least concentrated solution is Solution A, Solution D, Solution C, and Solution B

Step-by-step solution

Definition of concentration

The amount of a substance in a defined space is known as concentration.

Arrangement of solutions from most to least concentrated

In the given picture,

• Solution A is most concentrated because it contains 4 molecules in 1 liter of solution
• Solution D is the second most concentratedbecause it contains 6 molecules in 2liter, 3 molecules per literof solution.
• Solution C is third most concentrated because it contains 4 molecules in 2 liters, 2 molecules per literof solution
• Solution B is the leastconcentrated because it contains 6 molecules in 4 liters , 1.5 molecules per literof solution.

The solutions in an order from most to least concentrated is Solution A, Solution D, Solution C, Solution B
