how much propane will i use i will be building an ig pool and ig spa 7ft spa i will be heating the spa with a 400k btu propane heater i would like to heat the pool a couple of time per year for special events local code limits the size of a propane tank to 125 gallons anything bigger will require a permit from the fire dept
(c) The heat of combustion of propane is -2,220.1 kJ/mol. Calculate the heat of formation, ïHfï°, of propane given that ïHfï° of H2O(l) = -285.3 kJ/mol and ïHfï° of CO2(g) = -393.5 kJ/mol.(d) Assuming that all of the heat evolved in burning 60.0 grams of propane is transferred to 8000 grams of water (specific heat = 4.18 J/g.alculate the heat of formation, ïHfï°, of propane given that ïHfï° of H2O(l) = -285.3 kJ/mol and ïHfï° of CO2(g) = -393.5 kJ/mol.
