How much carbon dioxide is produced upon the complete combustion of 17.3L of propane (approximately content of one 5-gal tank)? Assume that the density of the liquid propane in the tank is 0.621 g/mL.

Question

Can you please list the steps! I am really confused! I tried many ways but I can't find the way to figure it out.

Answer 1

1. Write and balance the equation.
C3H8 + 5O2 ==> 3CO2 + 4H2O

2. grams C3H8 = volume x density = ?

3. mols C3H8 = grams/molar mass = ?

4. Using the coefficients in the balanced equation, convert mols C3H8 to mols CO2.

5. Convert mols CO2 to grams CO2. g = mols x molar mass = ?
