NCERT · Class 11 · Chemistry · Some Basic Concepts of ChemistryThe total number of atoms present in 1 mole of oxygen gas ($O2$) is:
Step-by-Step Solution
1 mole of $O_2$ molecules contains $6.022 \times 10^{23}$ molecules. Since each $O_2$ molecule has 2 atoms of oxygen, total number of atoms $= 2 \times 6.022 \times 10^{23} = 1.2044 \times 10^{24}$ atoms.
