C3H8(g) + 5O2(g) ->3CO2(g) + 4H2O(l) Ho = -2,220 kJ/mol
Propane is often used for gas grills and is typically purchased by filling a propane tank with 20 pounds of propane. What is the enthalpy change when 18 pound of propane is burned? Use the conversion 1 lb = 454 g and express your answer in scientific notation. For example use 2.3e-5 to indicate a number such as 2.3 x 10-5.
