Question

In an ion with an unknown charge, the total mass of all the electrons was determined to be 1.640 x t/?f=10%5E%7B-26%7D" id="TexFormula1" title="10^{-26}" alt="10^{-26}" align="absmiddle" class="latex-formula"> g, the total mass of its protons was 4.015 x $10^{-23}$ g, and the total mass of its neutrons was 4.690 x $10^{-23}$ g. What is the identity, charge, and mass number of this ion? Electron one mass = 9.109 x $10^{-31}$ Proton one mass = 1.673 x $10^{-27}$ Neutron one mass = 1.675 x $10^{-27}$

Answer 1

D should be the answer from 1.675 x 10 -/23
