What amount of substance is contained in 100g of CuSO4?

In order to find the amount of a substance in a certain mass of salt, you must first determine the molar mass of the salt.

Let’s find the molar mass of copper sulfate. To do this, we add up the molar masses of the atoms that enter the molecule.

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

Let’s find the amount of a substance by dividing the mass of a substance by its molar mass:

N CuSO4 = 100/160 = 0.625 mol;
