Question 20One commonly used precise way to describe concentrations of solutions is to state _____.

A)that the solution is dilute or concentrated

B)the percentage by area of the solute

C)the percentage by volume of the solute

D)the percentage by volume of the solvent

Answers

Answer:

The commonly used pieces to describe concentration of a solution is to state the percentage by volume of the solute. Hence the correct answer is option c.

Explanation:

A solution is said to be concentrated or dilute by the amount of solute and the amount of solution in it. A solution is defined as the mixture of solute into solvent. A solution is properly set if it is dilute or concentrated by seeing and observing it.

By defining the solution to its percentage volume that is calculated on the concentration of solute is the more precise method to tale about the concentration of the solution. This precise method can be used for many scientific experiments and further use.
