The standard disposable propane cylinders for use with camp stoves, lanterns, portable barbecues, etc, contain 355 g of propane. Calculate the total energy available from one of these cylinders.

Answer 1

C3H8 + 5O2 == 3CO2 + 4H2O

Look up the delta H for this reaction or calculate it from
dHrxn = (n*dHo products) - (dHo reactants) = ?
Then that is the dH for the reaction for 44 g C3H8. Call that Y.
Then Y x (355/44) = ? energy available.

Answer 2

Alright thank you so much for your help! I really appreciate it.

Answer 3

You're welcome.
