How many grams of water and sugar are needed to prepare 500g of a 3% sugar solution?

Let’s calculate the masses of the components of the solution.

To do this, it is necessary to multiply their mass fraction by the weight of the solution.

Let’s calculate the weight of the dissolved sugar.

M sugar = 500 x 0.03 = 15 grams;

In the same way, we find the weight of the solvent (water).

(In the calculations, we take the density of water equal to 1 gram / cm3).

M water = 500 x 0.97 = 485 grams = 485 ml;

Let’s check. To do this, add the masses of the components of the solution and get the mass of the required solution.

15 + 485 = 500;
