Acetylene gаs is used in welding. Ethylene gаs is the precursоr tо the plаstic pоlyethylene. The gas we call natural gas is primarily methane gas with smaller amounts of ethane gas. Propane gas fires up the backyard barbecue grill. Butane gas is the fuel in lighters. All six of these fuels are compounds that only contain the elements carbon and hydrogen. Answer the following questions in the corresponding space on the chart below. Use the same format as the examples shown. (6 points total) Acetylene has a carbon-to-hydrogen atom ratio of 1 to 1. What is the carbon-to-hydrogen mass ratio for this compound? (1 point) Ethylene has a carbon-to-hydrogen mass ratio of 6 to 1. What is the carbon-to-hydrogen atom ratio for this compound? (1 point) Ethane has a carbon-to-hydrogen atom ratio of 1 to 3. But, one mole of this gas weighs 30 g, not 15 g. What is the molecular formula of ethane? (1 point) *Note: subscripts won’t work, use the format CnHm for CnHm. Methane has a carbon-to-hydrogen mass ratio of 3 to 1 and a molecular weight of 16 g/mol. What is the molecular carbon-to-hydrogen atom ratio for this compound? (1 point) Propane has a carbon-to-hydrogen mass ratio of 9 to 2. One mole of this compound is 46 g/mol. What is carbon-to-hydrogen atom ratio for this compound? (1 point) Butane has a carbon-to-hydrogen atom ratio of 2 to 5. What is the carbon-to-hydrogen mass ratio for this compound? (1 point) Compound C-to-H Mass Ratio C-to-H Atom Ratio Molecular Formula Acetylene [acetylene] 1:1 Ethylene 6:1 [ethylene] Ethane 1:3 [ethane]* Methane 3:1 [methane] Propane 9:2 [propane] Butane [butane] 2:5
