Step 1: Identify the number of protons, neutrons, and electrons in the isotope.
The problem states that there are 8 protons, 10 neutrons, and 8 electrons in the isotope.
Step 2: Recall the definition of atomic mass.
Atomic mass is the mass of an atom, usually expressed in atomic mass units (amu). It is determined by the number of protons and neutrons in the atom's nucleus. Electrons are not considered in calculating atomic mass because they are significantly lighter than protons and neutrons.
Final Answer
The atomic mass of the given isotope of oxygen is approximately 18 amu.
