Study Notes
Solution Terminology
- A solution with a relatively large amount of solute is described as concentrated.
- The term concentration expresses the quantity of solute contained in a given amount of solution.
Solution Components
- The solute is the substance being dissolved in a solution.
- The amount of matter in an object is measured using the term mass.
Concentration Expressions
- When the solute is a solid, the concentration of a solution can be conveniently expressed using mass/volume percentage.
- The percentage of solute in a solution can be more easily determined by calculating the mass/volume percentage.
Concentration Calculation
- The formula used to calculate Mass/Volume percent is: (mass of solute / volume of solution) x 100%.
Concentration Measures
- Molarity is a measure of concentration that describes the number of moles of solute per liter of solution.
- Molality is a measure of concentration that describes the number of moles of solute per kilogram of solvent.
- Percent by Volume concentration is calculated by expressing the volume of solute as a percentage of the total volume of the solution.
- Molarity is the concentration measure that uses moles in its definition.
