Vedclass · Answer

(A) The percentage of $C$ is $92.3 \%$. Therefore,the percentage of $H$ is $100 - 92.3 = 7.7 \%$.

	
		
			Element
			Relative number of atoms (Percentage / Atomic mass)
			Simple ratio
		
	
	
		
			$C$
			$92.3 / 12 = 7.69$
			$7.69 / 7.69 = 1$
		
		
			$H$
			$7.7 / 1 = 7.70$
			$7.70 / 7.69 \approx 1$
		
	


The ratio of $C:H$ is $1:1$.
Therefore,the empirical formula is $CH$.

An organic compound containing $C$ and $H$ has $92.3 \%$ of carbon. Its empirical formula is:
