Explanation:

1 mole sodium carbonate contains 3 moles of oxygen atoms

hence, 0.1 moles of sodium carbonate contain 0.3 moles of oxygen atom

1 mole of oxygen atom =6.022×10²³

0.3 mole of oxygen atom=0.3×6.022×10²³

= 1.81×10²³ oxygen atom

hence,0.1 mole of sodium carbonate contains 1.81×10²³ oxygen atom
