How much copper sulfate is needed for the preparation of 0.5 liters of solution.

How much copper sulfate is needed for the preparation of 0.5 liters of solution. The molar concentration of CU S in which is 0.3 mol?

Let’s find the required amount of substance to prepare this solution.

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

In order to prepare such a solution, it is necessary to weigh and dissolve 0.5 x 0.3 = 0.15 mol of salt in water.

Let’s calculate the required weight of salt.

To do this, we find the product of the molar weight of the salt and the amount of substance.

M CuSO4 = 64 + 32 + 16 x 4 = 160 grams / mol;

m CuSO4 = 0.15 x 160 = 24 grams;
