Question

Explain the term “percentage of Solution“ and write four ways to express the “percentage of

solutions” ?​

Answer 1

A percentage solution is an amount or volume of chemical or compound per 100 mL of a solution. It is a relative expression of solute to solvent: X amount/100 ml = X% Percentage solutions are a convenient and easy way to record solution concentrations.

One way to describe the concentration of a solution is by the percent of a solute in the solvent. The percent can further be determined in one of two ways:

(1) The ratio of the mass of the solute divided by the mass of the solution

(2) The ratio of the volume of the solute divided by the volume of the solution.

(3) Chemists can express concentrations in various ways including: Molarity (M), Parts per million (ppm), % composition, or gram/Liter (g/L).

(4) Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution.
