Consider the combustion of propane gas, C3H8(g) + 5O2(g) 3CO2(g)+ 4H2O(l) Ho = -2,220 kJ/mol Propane (just C3H8) is often used forgas grills. Anyone who has every filled or moved those tanks knowsthey can get pretty heavy. a) How many grams of propane are in 1pounds of propane? Use the conversion 1 lb = 454 g. (Express youranswers for the next three questions in scientific notation. Forexample use 2.3e-5 to indicate a number such as 2.3 x 10-5.) gramsb) How many moles of propane are in 1 pounds of propane? molesc)How much heat can be obtained by burning 1 pounds of propane?(Remember to look at this from the viewpoint of the surroundings,since the question asks how much heat can be OBTAINED.) kJ What isthe enthalpy change for 12 CO2(g) + 16 H2O(l) 4 C3H8(g) + 20 O2(g)(Hint: compare this equation to the combustion equation forpropane.
