Question

Сколько граммов соли в 3 кг 4%-го солевого раствора? Пожалуйсто с объяснением

Answer 1

3 кг = 3 * 1000 = 3000 г
составим пропорцию:

3000 г --- 100%
   х г   ----  4%

х = (3000*4) : 100 = 120 г

Ответ: 120 грамм.  

Answer 2

Calculating the Amount of Salt in a 4% Salt Solution

To calculate the amount of salt in a 4% salt solution, we can use the formula:

Amount of salt = (Percentage of salt / 100) * Total solution weight

In this case, the total solution weight is 3 kg.

Using the given percentage of salt (4%) and the total solution weight (3 kg), we can calculate the amount of salt in the solution.

Amount of salt = (4 / 100) * 3000 grams

Amount of salt = 0.04 * 3000 grams

Amount of salt = 120 grams

Therefore, in a 3 kg 4% salt solution, there are 120 grams of salt
