What is a solution in chemistry?

Back

A solution is a homogeneous mixture composed of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

How do you calculate the concentration of a solution?

Back

Concentration is calculated by dividing the amount of solute by the total volume of the solution, often expressed as a percentage (e.g., mass/volume %).

What is the formula for mixing two solutions of different concentrations?

Back

The formula is C1V1 + C2V2 = CfVf, where C is concentration, V is volume, and f denotes the final mixture.

How do you set up an equation for the sum of two consecutive even integers?

Back

Let the first even integer be x. The next consecutive even integer is x + 2. The equation for their sum is x + (x + 2) = total.

How do you find the original price of an item after applying a discount?

Back

To find the original price, add the discount amount back to the final price. For example, if the final price is $42 after a $2 discount, the original price is $42 + $2.

What is the relationship between volume and concentration in a solution?

Back

The volume of a solution and its concentration are inversely related; as the volume increases, the concentration decreases if the amount of solute remains constant.

How do you convert a percentage concentration to a decimal?

Back

To convert a percentage to a decimal, divide the percentage by 100. For example, 20% becomes 0.20.

What is the process of dilution in chemistry?

Back

Dilution is the process of reducing the concentration of a solute in a solution, typically by adding more solvent.
