First we need to calculate the moles and then after the number of atoms to proceed further,
Moles of copper => 3.11/63.5 = 0.0489
Number of atoms => 0.0489 * Na => 0.0489 * 6.023 * 10^23 => 0.294*10^23
Number of protons = > 0.294*10^23*29 = > 8.55*10^23
Number of electrons = > Number of protons => 8.55*10^23
Total number of charges = > 8.55*10^23 + 8.55*10^23 => 17.11 x 10^23
