When comparing two solutions with the same volume, you may say that one is dilute and the other is concentrated. what does this mean?

a.
the dilute solution contains more solute than the concentrated solution.
b.
the dilute solution contains less solute than the concentrated solution.
c.
the two solutions are the same.
d.
the concentrated solution contains less solute than the dilute solution.

B. The dilute solution contains less solute than the concentrated solution.

Explanation:

A diluted solution is a solution that has less solute (what is being dissolved) dissolved in the solvent (what is dissolving). A concentrated solution is the opposite, it has more solute than dissolved by the solvent.

A simple example is when you make iced tea (with powder). If you want a strong taste, you add more iced tea powder (solute) to the water (solvent) so it is more concentrated. If you want less, you add more water to dilute it.  

c, liquids evaporate, creating a gas
