Answer 2

The percentage composition of the solution is $20\%$.

Explanation:

• A substance's mass fraction in a mixture is the ratio of that substance's mass to the mixture's overall mass.

• The most frequent way to express the percentage concentration of any solution is in mass percent.

• Note: When we talk about the mass or volume of a solution, we're referring to the sum of the masses and volumes of all of the solution's components. In the denominators of the preceding formulas, DO NOT include the mass or volume of only the solute or solvent.

Formula:

Mass by Volume percentage$=\frac{Mass of solute in grams}{Volume of solution}\times100$

∴ $\frac{4}{20}\times100$

⇒ $20\%$
