Question

If one mole of oxygen atoms weigh 16 grams find the mass of one atom of oxygen in gram ​

Answer 1

We know that 1 mole of oxygen contains 6.022 × 1023 oxygen atoms. Hence, 1 atom of oxygen molecule weighs 2.65 × 10-23 grams.

Answer 2

Answer:

The mass of one atom of oxygen is 2.65×10⁻²³g

Explanation:

given that,

      mass of 1 mole O = 16g

we know that,

   number of particles = number of moles × Avogadro's number

then,

     number of atoms of O = 1 × 6.022×10²³  

so, 1 mole of oxygen atoms contain  6.022×10²³ atoms

    mass of 6.022×10²³ atoms = 16g

                  mass of one atom = 16 / 6.022×10²³ = 2.65×10⁻²³g

Hence, the mass of one atom of oxygen is 2.65×10⁻²³g
