In chemistry, the concentration of a substance in solution is determined by molarity, which is symbolized by "M". This indicates the number of moles of a substance dissolved in one liter of a solvent (usually water).
For example:
- 1 mole of sodium chloride = 58 grams
- If 116 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 2-molar (2 M) solution of sodium chloride.
- If 232 grams of sodium chloride are dissolved in 1 liter of water, then that solution is a 4-molar (4 M) solution of sodium chloride.

Is the amount of a substance in a given volume the concentration of the substance?
Ye.. the concentration of a substance is measured as the amount of substance per unit volume. Accordingly, the amount of a substance in per unit volume is the concentration of the substance.
What do concentration tell you?
Concentration indicates the amount of solute present in a solution. It provides information about the strength or intensity of a substance in a given volume of solution. Different types of concentration (e.g., molarity, molality) provide different ways to express this relationship.
What is molarity a measurment of?
The concentration of a substance dissolved in a liquid.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
Do moles express concentration?
Yes, the mol is the SI unit of concentration.
