The mass of the solution is 150 grams;
To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.
m salt = 150 x 0.06 = 9 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m water = 150 – 9 = 141 grams;
Check: 141 + 9 = 150;
