A hydroxide ion, "HO-".
A small difference of mass exist because the gain or loss of electrons.
The mass number of an ion is calculated by adding the number of protons and neutrons. Since the ion has 107 electrons and a charge of +1, it must have 108 protons (107 electrons + 1). Therefore, the mass number is 108 protons + 158 neutrons, which equals 266. Thus, the mass number of the ion is 266.
Make sure you have the a as a small a. Na is sodium. As an ion it has a +1 charge, therefore positive
The problem statement that the ion has a plus 1 charge means that there is one more proton than electron in the ion. Therefore, the ion contains 106 protons and 157 neutrons and thus has a mass number of 106 + 157 or 263 amu.

The molar mass of ammonium ion NH4+ is approximately 18.038 g/mol.
266
This is the ion of the isotope Pb-208 (Pb2+).
The mass of an ion with 107 electrons would depend on the specific element of the ion. You would need to know the atomic number of the element to calculate the mass accurately using the atomic mass of the element.
The mass number of an ion remains the same as the element. This is because an ion gains or loses electrons which have minimal mass.
If the ion has a +1 charge and has 107 electrons, that means that it originally had 108 electrons, and therefore has 108 protons. The mass number is the sum of the protons and neutrons, 108 + 159, and therefore is equal to 267.
The element is cesium (Cs) and the cation is Cs^1+
