Question

Calculate the percentage concentration of acetic acid (CH3COOH), if the mass of the acid (CH3COOH) is 30 g, and the mass of water is 170 g​

Answer 1

Перевод: Рассчитайте процентную концентрацию уксусной кислоты (CH3COOH), если масса кислоты (CH3COOH) составляет 30 г, а масса воды - 170 г.

Решение:

30 г + 170 г = 200 г

200 г - 100%

30 г   - х

х = 300 * 100 / 200 = 15%

Ответ: 30 г - 15% , 170 г - 85%

Answer 2

To calculate the percentage concentration of acetic acid (CH3COOH) in the solution, we'll use the following formula:

Percentage Concentration = (Mass of Acetic Acid / Total Mass of Solution) * 100

Given: Mass of acetic acid (CH3COOH) = 30 g Mass of water = 170 g

Total Mass of Solution = Mass of Acetic Acid + Mass of Water Total Mass of Solution = 30 g + 170 g = 200 g

Now, let's calculate the percentage concentration:

Percentage Concentration = (30 g / 200 g) * 100 Percentage Concentration = 0.15 * 100 Percentage Concentration = 15%

The percentage concentration of acetic acid (CH3COOH) in the solution is 15%.
