Question

How do you make a 2 percent solution?

Answer 1

Hint To solve this question, first we have to understand the term solution, solvent and solute. A solution is a mixture of solute and a solvent.

Complete step by step solution:
A solution is a mixture in which the minor component is uniformly distributed into the major component. Solute is the chemical substance which dissolves in the substance. Solvent is in a generally liquid or gaseous state in which the solute dissolves to form a solution.
To make a proper 2 percent solution, they should specify a solvent but the general way to make a 2 percent solution is to get 2 grams of solvent and dissolve it in 98-100 ml of water.
Percentage of mass will be is calculated by dividing the mass of the component with the total mass of the mixture, then the result is multiplied by 100:
$\dfrac{2g}{100{{g}_{\text{mass of solute+ mass of solvent}}}}\times 100$

Additional information:
A saturated solution is a solution which contains the maximum amount of solute which is capable of being dissolved in the solution. On the other hand, unsaturated solution is the solution which the amount of solvent which dissolves in the solute is less than that of the value of equilibrium solubility.

Note: Like molality and molarity, mass percent is also a way to express the concentration of a solution. The mass percent is calculated by dividing the mass of the component with the total mass of the mixture, then the result is multiplied by 100. Normality is also a way to define the concentration of a solution.
