Question

solutions with which of the following molar concentrations are considered to be dilute?
1.0 mol/l
2.0 mol/l
0.1 mol/l or less
0.5 mol/l
a solution that contains the maximum quantity of a solute at a specific temperature is
saturated
unsaturated
supersaturated
dissolved

Explanation:

For the first question: Dilute solutions are defined as having a relatively low molar concentration, typically 0.1 mol/L or less, as concentrations above this are considered more concentrated.
For the second question: A saturated solution is specifically defined as a solution that holds the maximum amount of solute that can dissolve at a given temperature and pressure, with no more solute able to dissolve under those conditions.

Answer:

1. 0.1 mol/L or less
2. saturated
