The atomic mass of oxygen is 16u, this means one atom of oxygen is 16 times heavier than 1/12 th of carbon atom. Absolute mass or Actual atomic mass: It is found that, the actual atomic mass of a carbon-12 atom is equal to `1.9926 xx 10^(-23)`g. Atomic mass of an element is the relative mass of its atom as compared with the mass of a carbon-12 atom taken as 12 units.Hence, atomic mass of oxygen is 16 u means that one atom of oxygen is 16 times heavier than 1/12 of a carbon-12 atom. Mass of one atom of oxygen is. From www.PhysicsAccordingtoPalladino.orgCalculating the Mass of an Oxygen Atom and molecule from the periodic table. Mass of 1 atom of oxygen = 2.66.10⁻²³ g Mass of 1 mole of oxygen atoms = mass of 1 atom. number of atoms in 1 mole Mass of 1 mole of oxygen atoms = 2.66.10⁻²³ g. 6.02.10²³ = 16. 01 g Mass of a glass of water = 0.050 Kg or 50 g.

Please find below the solution to the asked query:
Answer is option d.
One atom of O has 8 protons and 8 neutrons. Mass of proton or neutron is 1.66 10-24 g.
Mass of 16 nucleons = 16 ( 1.66 10-24) g
Mass of an oxygen atom is 16 amu and in terms of gram atomic mass mass of 1 mole is 16 g.
Mass of 1 oxygen atom = 16/ 6.022 X 1023 g {1 mole contains 6.022 X 1023 particles)
Hope this information will clear your doubts about mass of an oxygen atom.
