<h3><u>Answer;</u></h3>
A. <em>18 hydrogen atoms </em>
<h3><u>Explanation;</u></h3>
- <em><u>Alkanes are group of hydrocarbon that are saturated</u></em>. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
- <em><u>The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.</u></em>
- Therefore,<u><em> an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. </em></u>Thus, the formula of the hyrocarbon will be; C₈H₁₈.
