How many grams of sodium chloride and how many milliliters of water must be taken to prepare 600 g

How many grams of sodium chloride and how many milliliters of water must be taken to prepare 600 g of saline, the mass fraction of salt in which is 0.9%.

The mass of the solution is 600 grams;

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

m of salt = 600 x 0.9 / 100 = 5.4 grams;

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

m of water = 600 – 5.4 = 594.6 grams;

The density of water is 1 gram / cm3. To prepare this solution, you must measure out 594.6 milliliters of water.

Check: 594.6 + 5.4 = 600;
