| **Calculate the masses of salt and water required to prepare the solution. The mass of the required NaCl solution is 50g. but. the mass fraction of salt in the solution is 3%.**

The mass of the solution is 50 grams;

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

m salt = 50 x 0.03 = 1.5 grams;

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

m of water = 50 – 1.5 = 48.5 grams;

Check: 1.5 + 48.5 = 50;
