How much salt and water should you take when preparing 200 grams of a solution with w = 6%?
| June 19, 2021 | education
The mass of the solution is 200 grams;
To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.
m salt = 200 x 0.06 = 12 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m of water = 200 – 12 = 188 grams;
Check: 188 + 12 = 200;
