Mass of one atom of oxygen is (a) 23 16 g 6.023 10 × (b) 23 32 g 6.023 10 × (c) 23 1 g 6.023 10 × (d) 8u ← Prev Question Next Question → 0 votes 862 views. If the mass of one atom of oxygen is 16.00 amu, what is the mass of one mole of elemental oxygen (O2) in grams? Atomic mass of oxygen = 16gm Molar mass of oxygen = (16×2)gm =32gm Mass of 1 mole of any molecule is equal to its molar mass. Thus, mass of 1 mole of oxygen is = 32gm.
When the mass number of oxygen is 16, how many neutrons does oxygen have in its nucleus?

Explanation:
Mass number equals number of sub atomic particles in the nucleus.
Atomic number gives the number of protons, which equals the number of electrons. The atomic number for oxygen is 8, so the atom has 8 electrons and 8 protons.
Protons and neutrons are found in the nucleus, so the number of neutrons is found by subtracting the proton number from the mass number I.e. 16 - 8 = 8
Oxygen exists in isotopic form and has an isotope with mass number 18. This atom will have 10 neutrons as 18 - 8 = 10
Explanation:
Oxygen has an atomic number of
We got the mass as
