March 25, 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 0.05 = 10 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m water = 200 – 10 = 190 grams;
Check: 190 + 10 = 200;
