How much sodium chloride is required to prepare 100 ml of 0.1 m solution?

Determine the required amount of a substance for preparing a solution.

To do this, multiply the volume of the solution by its molar concentration.

In order to prepare such a solution, it is required to hang and dissolve in water 0.1 x 0.1 = 0.01 mol of salt.

Let’s calculate the required weight of salt.

To do this, we multiply the molar weight of the salt by the chemical amount of the substance.

M NaCl = 23 + 35.5 = 58.5 grams / mol;

m NaCl = 0.01 x 58.5 = 0.585 grams;
