upon complete combustion, a 1.00L sample ( at STP) of a natural gas gives off 43.6KJ of heat. If the natural gas is a mixture of CH4(g) and C2H6(g), what is the volume of methane in mL in the sample? keep 3 sig. figs.

useful information: CH4(g) + 2O2(g) --> CO2(g) + 2H2O(l) deltaH= -890.3KJ/mol

C2H6(g) + 7/2O2(g) --> 2CO2 (g) + 3H2O(l) deltaH= -1559.7KJ/mol

      Hello BrachiosaureRouge364,

      Thank you very much for your question! You can note that this exchange will be archived for the purposes of improving our services and research. The Alloprof platform specializes in primary and secondary services. Since your question goes beyond elementary and secondary school requirements, I do not have the necessary resources to help you. I therefore suggest that you write to your teacher in order to get a complete answer.

      Thank you and good day!
