Answer 1

Можно решить уравнением Пусть х кислота 1,2х это вода
Уравнение:
х+1,2х=20
2,2х=20/:2,2
х=дальше сам

Answer 2

Calculating the Amount of Water and Concentration of the Solution

To calculate the amount of water and the concentration of the solution, we can use the following steps:

1. Determine the Total Weight of the Solution: - Let's assume the total weight of the solution is 20 kg.

2. Calculate the Amount of Acid: - Since the solution contains 1.2 times more water than acid, we can set up the following equation: - Let x be the weight of the acid in kg. - Then the weight of the water will be 1.2x kg. - The total weight of the solution is the sum of the weight of the acid and the weight of the water: x + 1.2x = 20 kg.

3. Solve for the Weight of the Acid: - Solving the equation x + 1.2x = 20 will give us the weight of the acid.

4. Calculate the Concentration of the Solution: - Once we have the weight of the acid and the weight of the water, we can calculate the concentration of the solution.

Let's proceed with the calculations.
