In composition of natural gas, 0.17% is constituted by:
Correct answer: C. Butane
- A. Methane
- B. Ethane
- C. Butane
- D. Nitrogen
Explanation
Natural gas has Methane and ethane contributing to large portions with Methane being 90%, approximately, and ethane, up to 5%. The remaining being propane and butane exist in small proportions. As propane is not given as an option, we can safely assume our answer to be butane as Nitrogen is not found in natural gas.
