    Answer: mass number of oxygen is 17.

    Explanation:

    Atomic number is defined as the number of protons or number of electrons that are present in an atom.

    Atomic number = Number of electrons = Number of protons = 8

    Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

    Mass number = Number of protons + Number of neutrons = 8 + 9 = 17

    Hence, mass number of oxygen is 17.
