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.

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.
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 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.
What does mM stand for in biology?
mM stands for millimolar, which is a unit of concentration used to express the concentration of a substance in a solution. It indicates the number of millimoles of a substance per liter of solution.

What is molarity a measurment of?
The concentration of a substance dissolved in a liquid.
What is the amount in an object or substance?
The amount [of stuff] in an object or substance is its mass.
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.
When the concentration of a substance differs from one area to another this is called concentration?
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
What does pg mL stand for?
pg mL stands for picograms per milliliter, which is a unit of measurement used to express the concentration of a substance in a liquid.
Do moles express concentration?
Yes, the mol is the SI unit of concentration.
Does molarity express concentration?
Yes
Solute per 100g of solvent is called what?
The concentration of a solute per 100g of solvent is called a percentage by weight. It is commonly used to express the concentration of a solute in a solution.
When there is no difference in the concentration of a substance from one area to another?
When there is no difference in concentration of a substance from one area to another, we refer to this as equilibrium. At equilibrium, there is an equal distribution of the substance, and there is no net movement of the substance in any particular direction.
