The mass of the solution is 400 grams;
To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.
m salt = 400 x 0.2 = 80 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m water = 400 – 80 = 320 grams;
Check: 320 + 80 = 400;
