## 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.
