Table 1 to Subpart Ja of Part 60—Molar Exhaust Volumes and Molar Heat Content of Fuel Gas Constituents

Constituent	MEV^a dscf/mol	MHC^b Btu/mol
Methane (CH₄)	7.29	842
Ethane (C₂ H₆)	12.96	1,475
Hydrogen (H₂)	1.61	269
Ethene (C₂ H₄)	11.34	1,335
Propane (C₃ H₈)	18.62	2,100
Propene (C₃ H₆)	17.02	1,947
Butane (C₄ H₁₀)	24.30	2,717
Butene (C₄ H₈)	22.69	2,558

^a MEV = molar exhaust volume, dry standard cubic feet per gram-mole (dscf/g-mol) at standard conditions of 68 °F and 1 atmosphere.
^b MHC = molar heat content (higher heating value basis), Btu per gram-mole (Btu/g-mol).
