How many grams of sugar and milliliters of water do you need to take to prepare 250 grams of a 12% solution of it?

In order to find the mass of a component, it is necessary to multiply the mass fraction of the component by its mass fraction.

M solution = 250 grams.

Let us find the masses of the components of the solution.

The sugar mass will be:

M sugar = 250 x 0.12 = 30 grams;

The mass of the solution will be:

M water = M water + M salt = 250 x 0.88 = 220 grams;

Check: 30 + 220 = 250;
