You asked: What mass of propane must be burned to supply 2775?

55.13 grams of propane is needed in order to produce 2775 kJ of heat.

What mass of propane would be required to supply kJ of heat?

Answer is: 55.125 grams of propane must be burned.

What mass of propane c3h8 must be burned?

Conclusion: 1.52 kg of propane must be burned.

What mass of propane would need to be combusted to release?

Thus, approximately, 1/5 of a mole of propane must be combusted with stoichiometric oxygen to evolve this amount of energy.

What mass of liquid ethanol c2h5oh must be burned to supply 500 kJ of heat the standard enthalpy of combustion of ethanol at 298 K is kJ mol?

The enthalpy of combustion of ethanol is widely quoted in the public domain and is 1360 kJ/mol. Therefore in order to supply 500 kJ of heat you would need to burn (500/1360) = 0.368 moles of ethanol. The molecular weight of ethanol is 46.07 g/mol, so the mass required would be 0.368 x 46.07 = 16.95 g.
