Question

how to determine the mass of one oxygen atom using Avogadro number​

Answer 1

Answer:

Molecular mass is obtained by multiplying the atomic mass of an element with the number of atoms in the molecule and then adding the masses of all the elements in the molecule. O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu

Answer 2

Answer:

1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? Molar mass (in grams) is always equal to the atomic weight of the atom! Molar mass (in grams) is always equal to the atomic weight of the atom!

Explanation:

1 mole = 6.022*10 raise to 23 = moleculartmass of an element

mass of oxygen elements = neutron + protons

8+8=16
