Question
Ethane and ethylene are two gases containing only hydrogen and carbon atoms. In a certain sample of ethane, $4.53 \mathrm{~g}$ of hydrogen is combined with $18.0 \mathrm{~g}$ of carbon. In a sample of ethylene, $7.25 \mathrm{~g}$ of hydrogen is combined with $43.20 \mathrm{~g}$ of carbon.(a) Show how the data illustrate the law of multiple proportions.(b) Suggest reasonable formulas for the two compounds.
Step 1
For ethane, we have 4.53 g of hydrogen and 18.0 g of carbon. So, the ratio is $\frac{4.53}{18.0} = 0.25167$. For ethylene, we have 7.25 g of hydrogen and 43.20 g of carbon. So, the ratio is $\frac{7.25}{43.20} = 0.167841$. Show more…

Ethane and acetylene are two gaseous hydrocarbons. Chemical analyses show that in one sample of ethane, $2.65 \mathrm{g}$ of carbon are combined with $0.665 \mathrm{g}$ of hydrogen, and in one sample of acetylene, $4.56 \mathrm{g}$ of carbon are combined with $0.383 \mathrm{g}$ of hydrogen. (a) Are these results consistent with the law of multiple proportions? (b) Write reasonable molecular formulas for these compounds.

Benzene, ethane, and ethylene are just three of a large number of hydrocarbons - compounds that contain only carbon and hydrogen. Show how the following data are consistent with the law of multiple proportions. $$ \begin{array}{lcc} \hline & \text { Mass of carbon in } & \text { Mass of hydrogen in } \\ \text { Compound } & 5.00 \mathrm{~g} \text { sample } & 5.00 \mathrm{~g} \text { sample } \\ \hline \text { Benzene } & 4.61 \mathrm{~g} & 0.39 \mathrm{~g} \\ \text { Ethane } & 4.00 \mathrm{~g} & 1.00 \mathrm{~g} \\ \text { Ethylene } & 4.29 \mathrm{~g} & 0.71 \mathrm{~g} \\ \hline \end{array} $$
