Add more or remove some of the substance from the mixture, or add or remove some other substance from the mixture. Removal is usually more difficult, with heating (distillation or boiling off) or filtration (of a solid) being among the most direct methods.

Can the concentration of the substance change if it is a gas?
Yes.
How can you change concentration?
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.
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.
What are some ways the density of a substance can be increased and decreased?
The increase in concentration increases the density and decrease causes the decrease in density.

Can the concentration of a substance change if it is an aqueous solution?
Yes. An aqueous solution means that at least one solute is dissolved in water. You can increase the concentration by adding more solute, or you can decrease the concentration by adding more water.

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.
What are some ways the density of a substance can be increased and decreased?
The increase in concentration increases the density and decrease causes the decrease in density.
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
How does the concentration of a pure liquid change throughout the course of a reaction?
The concentration of a pure liquid change throughout the course of a reaction decreases. This is because the substance is no longer pure.
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.
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 .
