Vedclass · Answer

(C) $1$. Calculate the molar mass of the hydrocarbon: $	ext{Molar mass} = 2 	imes 	ext{Vapor density} = 2 	imes 15 = 30 \ 	ext{g/mol}$.$2$. Determine the mass of carbon and hydrogen in one mole: $	ext{Mass of C} = 80\% 	ext{ of } 30 = 24 \ 	ext{g}$. $	ext{Mass of H} = 20\% 	ext{ of } 30 = 6 \ 	ext{g}$.$3$. Calculate the number of moles of each atom: $	ext{Moles of C} = \frac{24}{12} = 2$. $	ext{Moles of H} = \frac{6}{1} = 6$.$4$. The molecular formula is $C_2H_6$.

$A$ hydrocarbon contains $80\%$ carbon and its vapor density is $15$. What is the hydrocarbon?
