Question

Your teacher created a 2 g/L salt-water solution (solution A) and a 2.5 g/L salt-water solution (solution B), both in 500 mL of water. Using the concentration equation, which solution is more concentrated? How do you know?

Answer 1

Solution B,

A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute. However, these terms are relative, and we need to be able to express concentration in a more exact, quantitative manner.
