Question

If 16 g of oxygen contains 1 mope of oxygen atoms, calculate the mass of one atom of oxygen​

Answer 1

Answer: We know that 1 mole of oxygen atoms = 6.02 × 10^(23) O atoms .

Mass of one mole of atoms = 16 g

So, mass of one atom = 16 ÷ (6.02 × 10^23) = 2.65 ×10 ^ (-23) g.

Explanation:

Answer 2

Explanation:

1 mole=16gm=6.022*10^23 atoms

6.022*10^23 has mass= 16gm

1 atom has mass=16÷6.022*10^23

= 2.65*10^-23
