1 molecule of ethane contains 2 carbon atoms
so 3 moles of ethane contains 6 mole of carbon atoms.
1 molecule of ethane contains 6 hydrogen atoms
so 3 moles of ethane contains 18 mole of hydrogen atoms.
1 mole of ethane contains 6.023×10²³ molecules of ethane
so 3 mole of ethane contains 3×6.023×10²³ =18.069 ×10²³ molecules of ethane
