How much potassium chloride should be taken to prepare a 200ml 16 solution of 1.1g / ml?

Let’s calculate the weight of the dissolved salt.

M salt = 200 x 1.1 x 0.16 = 35.2 grams;

Similarly, we find the weight of the solvent (water).

(In the calculations, we will make the assumption that the density of water is 1 gram / ml).

M water = 200 x 1.1 x 0.84 = 184.8 grams = 184.8 ml;

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

35.2 + 184.8 = 220;
