Answer 2

Concept:

The amount of solute that has been dissolved in a specified amount of solvent or solution is determined by the solution's concentration.

Given:

Mass of solute: $20g$

Mass of solvent: $380g$

To find:

Concentration of the solution​

Solution:

Mass of solution= $20g + 380g= 400g$

Concentration of solution= $\frac{Mass of solute}{Mass of solution} * 100$

                                           $\frac{20}{400} *100 = 5$ %

Therefore, the concentration of the solution is 5%.
