January 16, 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 0.1 = 20 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m of water = 200 – 20 = 180 grams;
Check: 180 + 20 = 200;
