Omit the electrons, as their combined mass is very small compared to the mass of the nucleus. Congratulations! Now you have the atomic mass of that atom.

Why is Rubidium-87 used for Bose-Einstein condensates?

11. Rubidium-87 was the first and the most popular atom for making Bose–Einstein condensates in dilute atomic gases. Even though rubidium-85 is more abundant, rubidium-87 has a positive scattering length, which means it is mutually repulsive, at low temperatures. This prevents a collapse of all but the smallest condensates.
