Question

How many atoms are there in 1 mole of O^2

Answer 1

Answer:

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

Answer 2

Atomic number of Oxygen is 8. atomic mass = 16

1 Mole of Oxygen = 6.022×10²³ atoms

.O2= 2×6.022×10²³

=> 12.044×10²³ atoms
