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 is molarity a measurment of?
The concentration of a substance dissolved in a liquid.
Do moles express concentration?
Yes, the mol is the SI unit of concentration.
What determines the direction in a substance diffuses across a membrane?
The concentration gradient determines the direction in which a substance diffuses across a membrane. The concentration gradient is a measure of how the concentration of a substance changes from one place to another.
What is the difference between a solvent and concentration?
Solvent refers to a substance that will dissolve another substance. Concentration, in chemistry, refers to the amount (measure) of a substance that is mixed with another substance. It is most commonly used to describe the amount of a substance (solute) dissolved in another substance (solvent).

What is the amount in an object or substance?
The amount [of stuff] in an object or substance is its mass.
Do moles express concentration?
Yes, the mol is the SI unit of concentration.
Does molarity express concentration?
Yes
What is cells solution in which the concentration of dissolved substance in the solution is the same as concentration of dissolved substance inside a cell?
isotonic

Movement of a substance down the substance's concentration gradient?
diffusion
When the concentration of a substance differs from one area to another this is called concentration?
The concentration gradient is the difference in the concentration of a substance from one location to another. The plasma membrane controls the traffic .
What is 5 less then n?
(n - 5) This is how to express 5 less than n mathematically.
The difference in concentration of a substance across space is called a?
it is called a concentration gradient.
What is concentration (chemistry)?
Concentration is the amount of a substance in a specified mass (or volume) of a material.
