Find the mass of salt and the volume of water that will be required to prepare 3kg of 15%

Find the mass of salt and the volume of water that will be required to prepare 3kg of 15% brine for salting watermelons.

The mass of the solution is 3,000 grams;

To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.

m salt = 3000 x 0.15 = 450 grams;

To find the mass of water, subtract the mass of salt from the mass of the solution:

m water = 3,000 – 450 = 2,550 grams;

The density of water is 1 gram / cm3;

The volume of water is 2,550 x 1 = 2,550 ml.

Check: 450 + 2,550 = 3,000;
