Question

Whenever organic matter is decomposed under oxygen free conditions, methane is one of the products. Thus enormous deposits of natural gas, which is almost entirely methane, serve as a major source of fuel for home and industry (dHrxn for the combustion of CH4 = -802 kJ/mol.) What volume (in ft^3) of natural gas, measured at STP, is required to heat 1.00 qt of water from 25.0 degrees C to 83.50 degrees C (d of H2O = 1.00 g/mL; d of CH4 at STP = 0.72 g/L)?


I got 0.228 cubic feet.....is this right?

Answer 1

I obtained 0.226; I suspect we just didn't use the same conversion fators for one of the conversions.

Answer 2

Thank you so much for all your help!
