The density of water is 1g / cm³ => the mass is numerically equal to the volume = 100g.
Let’s calculate the mass of the solution ingredient: 400g * 20% = 400g * 0.2 = 80g.
The total mass of the resulting solution = 400g + 100g = 500g.
Let’s calculate the proportion of the ingredient in the final solution: (80/500) * 100% = 0.16 * 100% = 16%.
Answer: Received a 16% solution.
