| February 1, 2021 | education
The mass of the solution is 50 grams;
To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.
m salt = 50 x 0.1 = 5 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m water = 50 – 5 = 45 grams;
Check: 45 + 5 = 50;
