A magnesium-24 atom is ionized to form a 1224Mg2+^{24}_{12}\text{Mg}^{2+}1224Mg2+ ion.
What is the specific charge of this ion?
(Use the following values: mass of proton ≈ \approx\,≈ mass of neutron = 1.67 × 10-27 kg charge of electron = -1.60 × 10-19 C)
4.8×107 C kg−14.8 \times 10^7\text{ C}\text{ kg}^{-1}4.8×107 C kg−1
8.0×106 C kg−18.0 \times 10^6\text{ C}\text{ kg}^{-1}8.0×106 C kg−1
1.6×107 C kg−11.6 \times 10^7\text{ C}\text{ kg}^{-1}1.6×107 C kg−1
9.6×107 C kg−19.6 \times 10^7\text{ C}\text{ kg}^{-1}9.6×107 C kg−1
