The mass of the solution is 300 grams;
To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.
m salt = 300 x 0.05 = 15 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m of water = 300 – 15 = 285 grams;
Check: 285 + 15 = 300;
