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).
- 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.
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.
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
Yes, the mol is the SI unit of concentration.
It is the amount of a substance present in a mixture.
diffusion is the movement of a substance with respect to concentration and gradient a substance traveling with the concentration gradient ( simple diffusion) a substance traveling against the concentration gradient (active diffusion)
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
higher the concentration the slower it moves
Concentration of acid will decreases on dilution. Concentration means amount of 1 substance per unit amount of another substance in which 1st substance is dissolved or mixed. So if u increase the solvent( 2nd substance) i.e., on dilution, then the ratio '1st substance per unit 2nd substance' decreases. Hence concentration decreases.
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.
The concentration gradient is the difference in the concentration of a substance from one location to another. The plasma membrane controls the traffic .
Dilute it - if you add water or some other substance, you change the volume of the substance and thus change its concentration
the movement of any substance from a higher concentration to a lower concentration.
there is a concentration gradient!:)
Activetransportis the movement of a substance across a cell membrane against its concentration gradient (from low to high concentration).
