Question

Смешали 300 г 12,5% раствора или 275 г 35% раствора найти процентную концентрацию раствора. помогите пж пж Срочно​

Answer 1

Ответ:

23.26%

Объяснение:

Ну если срочно

W=((300*0.125)+(275*0.35))/(275+300)=0,2326 - 23.26%

Answer 2

Calculating the Concentration of the Solution

To find the percentage concentration of the resulting solution after mixing 300g of a 12.5% solution with 275g of a 35% solution, we can use the following formula:

Concentration of resulting solution = (Total amount of solute / Total amount of solution) * 100

First, let's calculate the total amount of solute and the total amount of solution.

1. Total amount of solute: - For the 300g of 12.5% solution: - Solute = 12.5% of 300g = 0.125 * 300g - For the 275g of 35% solution: - Solute = 35% of 275g = 0.35 * 275g

2. Total amount of solution: - Total amount of solution = 300g + 275g

Now, we can calculate the concentration of the resulting solution using the formula mentioned above.

Calculation

- Total amount of solute = (0.125 * 300g) + (0.35 * 275g) - Total amount of solution = 300g + 275g - Concentration of resulting solution = (Total amount of solute / Total amount of solution) * 100

Result

The concentration of the resulting solution is approximately 24.32%.

This calculation is based on the principles of mixing solutions and calculating the resulting concentration.
