Question

К 200 граммам раствора, содержащего 60% соли, добавили 400г раствора, содержащего 75% соли. Сколько процентов соли содержится в получившемся растворе?

Answer 1

200 * 0.6 = 120  г соли в первом растворе
400 * 0,75 = 300 г соли в первом растворе
420 / 600 *100% = 70% соли в новом растворе

Answer 2

Calculation of the Salt Content in the Solution

To calculate the percentage of salt in the resulting solution, we need to consider the amounts and concentrations of the two solutions that were mixed.

Let's break down the information given:

- 200 grams of a solution containing 60% salt - 400 grams of a solution containing 75% salt

To find the total amount of salt in the resulting solution, we can add the amounts of salt from each solution.

For the first solution: - 200 grams * 0.60 (60%) = 120 grams of salt

For the second solution: - 400 grams * 0.75 (75%) = 300 grams of salt

Adding the amounts of salt from each solution: - 120 grams + 300 grams = 420 grams of salt

To find the percentage of salt in the resulting solution, we divide the amount of salt by the total weight of the resulting solution and multiply by 100.

The total weight of the resulting solution is the sum of the weights of the two solutions: - 200 grams + 400 grams = 600 grams

Now we can calculate the percentage of salt in the resulting solution: - (420 grams / 600 grams) * 100 = 70%

Therefore, the resulting solution contains 70% salt.
