Question

У розчині міститься 42 кг солі як маса розчину якщо солі в ньому 35% .Срочно нужно плис!!!

Answer 1

1) 42 * 100 : 35 = 120 (кг) - масса

Ответ: 120 кг

Answer 2

                             42кг
маса розчину=-------------х100%= 120кг
                             35%
Ответ:маса розчину= 120 кг

Answer 3

Calculating the Mass of the Solution

To calculate the mass of the solution, we can use the formula:

Mass of solution = Mass of solute + Mass of solvent

In this case, the solute is the salt, and the solvent is the water.

Given: - Mass of salt (solute) = 42 kg - Percentage of salt in the solution = 35%

We can calculate the mass of the solution using the following steps:

1. Calculate the mass of the salt in the solution: - Mass of salt in the solution = (Percentage of salt / 100) * Mass of solution - Mass of salt in the solution = (35/100) * Mass of solution

2. Use the mass of the salt to find the mass of the solution: - Mass of solution = Mass of salt / (Percentage of salt / 100)

Let's calculate the mass of the solution using these steps.
