How many cu2 + ions are in a mole of cuso4?

One mole of CuSO4 contains one mole of Cu2+.

One mole of any substance contains Avogadro's number of ions.

Therefore, number of ions of Cu2 + can be calculated as follows:

number of ions = number of moles * Avogadro's number

number of ions = 1 * 6.02 * 10^23 = 6.02 * 10^23 ions
