For salting vegetables, an 8% sodium chloride solution with a density of 1.06 g / ml is used.

For salting vegetables, an 8% sodium chloride solution with a density of 1.06 g / ml is used. What is the mass of sodium chloride and how much water is required to prepare 20 liters of brine for pickling vegetables

The solution consists of two components. Dissolved substance and solvent.

The weight of the mortar is 20,000 x 1.06 = 21,200 grams.

Let’s calculate the weight of the salt.

To do this, multiply the weight of the solution by the mass fraction of the dissolved salt.

M salt = 21,200 x 0.08 = 1696 grams;

In a similar way, we calculate the weight of the solvent.

M water = 21,200 x 0.92 = 19,504 grams;

The density of water is 1 gram / cm3. Therefore, you need to measure 15,504 ml. water so that its weight in solution is 19 504 grams

Checking: M salt + M solvent = M solution = 1696 + 19504 = 21200 grams;
