Calculate the number of moles of carbon atoms in three moles of ethane.

Explanation

Ethane - Molecular formula = `C_(2)H_(6)`
1 mole of ethane contains 2 atoms of carbon `(6.023xx1O^(3)C)`
`:.` 3 moles of ethane contains 6 atoms of Carbon.
`:.` No. of moles of Carbon atoms = `3xx6.023xx10^(23)` Carbon atoms.
`= 18.069xx10^(23)` Carbon atoms
