Question

Имеется 20 л раствора Воды в нём на 50% больше , чем кислоты. а) Сколько л воды и сколько л кислоты ? б) Какова концентрация?

Answer 1

Х - кислота
0,5х - 50%
х + 0,5х - вода

х + х + 0,5х = 20
2,5 х = 20
х = 8 л - кислоты в растворе.

8 : 20 *100 = 40% - концентрация раствора.

Answer 2

Task: Calculating the Amount of Water and Acid in a 20L Solution

To calculate the amount of water and acid in a 20L solution, we need to know that the water content is 50% more than the acid content. Let's solve this step by step.

a) Calculating the Amount of Water and Acid: - Let's assume the amount of acid in the solution is x liters. - According to the given information, the amount of water is 50% more than the acid content. This means the amount of water is 1.5x liters. - The total volume of the solution is 20L, so we can write the equation: x + 1.5x = 20. - Simplifying the equation, we get 2.5x = 20. - Solving for x, we find x = 20 / 2.5 = 8. - Therefore, the amount of acid in the solution is 8 liters, and the amount of water is 1.5 * 8 = 12 liters.

b) Calculating the Concentration: - To calculate the concentration, we need to know the concentration of the acid in the solution. - Unfortunately, the concentration of the acid is not provided in the given information. - The concentration of a solution is usually expressed as the amount of solute (in this case, acid) dissolved in a given amount of solvent (in this case, water). - Without the concentration of the acid, we cannot determine the overall concentration of the solution.

In summary: a) The solution contains 8 liters of acid and 12 liters of water. b) The concentration of the solution cannot be determined without the concentration of the acid.
